- I think that there should not be a minimum score to obtain in the exam in order to pass the course if the 40 minimum points are already achieved.» (Acceptable)
- Maybe, we could increase the importance of quiz a little.» (Good)
- Quiz and projects are truly instructive. For project more effective helps could be offer by the assistants. Based on sample exams, the level of problems does not match with the level of exercises and the time duration of the course. » (Good)
- Quizes were tricky, and I think it is a good idea to have the quizes in the bigining of tutorial sessions but it would be better not to have tutorial sessions at 8 on Mondays, I wish they had been at 10.» (Good)
- Keep the same for next year also.» (Very good)

- Because I just attended one exercise session.» (No, not at all)
- Because of the traffic in the morning 0800 is a bad time for me, so i did not attend the quizzes. 0830 would be better.» (No, not at all)
- Visst, en quizz gör att man läser på inför övningen men den tar också bort fokus (och tid) från övningsuppgifterna. Personligen tycker jag det vore bättre att skippa quizzarna och dela ut ett specifikt problem, typ ett case, som ska lösas inför varje övning. På så sätt kan man behandla det som är väsentligt inför övningen. » (Somewhat)
- The time is too early!» (Somewhat)
- Sometimes the questions are not very clear, maybe this is due to the fact that they are so brief. I would have preferred to have the quizzes at some other time slot, not on Monday at 8 AM. Maybe the Wednesday tutorial class would be more adequate. Anyway, my opinion is that the quiz is a very good idea. » (Yes, to some extent)
- They motivated me to find the reason of why one answer was true and why others were false.» (Yes, to some extent)
- We didn"t have a quiz on Spread Spectrum, may be it can be included next time» (Yes, to some extent)
- The quizzes help to learn. I learnt of the wrong answer I chose. Now I know waht the correct answers are.» (Yes, to a large extent)
- Because of quizzes, I review what I"ve learned every week.» (Yes, to a large extent)
- All the quiz questions were nice. Some mathematical calculations related questions can be included.» (Yes, to a large extent)

5. Indicate your attendance on scheduled sessions


- As there is a bug in this question I write it clearly : 76-100% of attendance for both Lectures and Exercises.»
- I think there are some wrong with the selection choise, my anser is both over 90%.»
- Some problem in the browser prevents me from marking 76-100% in both. »
- Something is wrong here. I couldn"t choose 76-100% for both of them. »
- Tried to set both 76-100% but the form did not allow it.»
- In exercises more problems can be solved. The speed for solving the problems is too low. I recommend more solved problem, printed in a nice way, could increase the ability of students to a great extend to over come the final exams and more than that to gain insights in different concepts introduced in the course. »
- I attended 76-100% of Exercises but I can not choose it from thr multiple choices.»
- Exercise session on Monday was too early.»

- Good explanations, we are encouraged to ask questions and these questions are always answered adequately. Besides the slides, the complementary explanations on the blackboard are usually very good and clear. If time constraints allow it, doing some examples in class rather than pure theory could be of great help. » (Good)
- If there are the outlines like the book did, it would be better.» (Good)
- The notation in formulas could be more clear. For example, it is inconvenient that gamma denotes both SNR and path loss exponent. » (Good)
- no doubt...» (Good)
- The writing on board is good to change the mood from the slides. » (Good)
- I think some more time should have been spent on the coding part» (Good)
- Erik"s lectures were wonderful. He is one of the best. It is clear that he spends time on slides and lectures. That"s absolutely rewarding. Moreover, he is master over the concepts he teaches. That"s very inspiring. » (Very good)
- In some of the lectures days, the notes were hand written on the black board. Instead of that, include those information also into the slides and explain only the concepts in black board. This saves time for us.» (Very good)
- Lectures are quite good and helpful.» (Very good)

- They were not the type that helps learning, they were just numeric problems. It is better to have conceptual problems that are more related to understanding rather than applying formulas.» (Fair)
- I feel what is done in tutorials and what is explained in theory could be better connected. The introduction to each tutorial reviewing the theory is very helpful and should definitely be kept for the following years.» (Fair)
- I attended the exercises classes with Lotfollah. He is good at teaching and explaining the concepts. I think he needs to prepare more the solution of the problems, he made mistakes and sometimes is not very clear when he is doing the analysis of the problem. I know he doesn"t like to do things by heart, which is good. But sometimes he gets confused. That"s why is good he prepares the analysis of the problem.» (Acceptable)
- It"s better TA can prepare some copy of exercise tasks to student and do more focus on exercise not for no related topics. » (Acceptable)
- The scheduled amount of study hours for exercises seems to be not enough, because problems in the course take much time to solve, especially in the beginning.» (Acceptable)
- There were sometimes when the tutors got confused when trying to solve the exercises, that caused confusion between the students» (Acceptable)
- I felt like, at least for a couple of exercise sessions, teaching assistants came to class without enough preparation. They struggled to answer the questions.» (Acceptable)
- Give some time for students to think about the questions, that helps.» (Good)
- very helpful» (Good)
- I just attended 1 session that was quite helpful...» (Good)
- The selected exercises were good. But some of the exercises from the book are simply uses formulas instead of wireless communication concepts. Please change the text book questions for the next year.» (Good)

8. How would you rate the quality of the course material (with respect to your learning)?


- Something id wrong with the selection. The text book is good and Selected exercises as well. »
- It should be very good on exercises»
- For some concepts, the book does not clarify clearly.»
- The selected exercises where good. Much better than the ones from the book.»
- Selected exercises should cover wider context for the next time.»

9. How would you rate the quality of the projects (with respect to your learning)?


- Here again... Both are very good»
- The second project had some problems and the procedure were not explained clearly. »
- I think that the second part has a big working load and that the student does not learn as much as with the first project»
- Very Good/Good»
- It could be more challenging.»
- Less routine work and more experimentation would be better. There was so much programming and debugging that no time left for anything else.»
- Both very good. One important point: More helps from the assistants are expected in both projects. Maybe the drawback with the projects was this.»
- Break up the project report marks into requirements and results. Inform that in the project memo. »
- For some parts of projects, it is similar to projects of other course(i.e Applied signal process). Thus, it seems less interesting.»
- It was not possible to select the same box for choices on the same row for some reason. The projects were very good.»
- There is something wrong with the answering sheet that i couldn"t select properly. They were quite beneficial but project memos may be more clear.»
- enjoyed the projects»

- I felt that we had less time for project 1. »
- Again, both "Just right amount of work"»
- The work wasn"t really too much , but it prevented me from reading the text regularly and following the lecture notes»

- Keep the same work load.» (Just right amount of work)
- There were so many lectures, and in the first few weeks 3 lectures per week, so make it hard to follow till the end.» (A bit too much work)
- to manage the project and at the same time to keep up with the lectures is bit hard...» (A bit too much work)

- I was disappointed that the cellular system themes was treated so shortly and at the end. I would expected to see it at the beginning and much more deeper. In general the course was opaque by all the formulas needed to be used, this caused that the essence of the concepts behind those formulas got lost. » (Acceptable)
- Would have been great with 10 to 15 more days so that some more things could be covered. » (Good)
- The lectures were given in such a way that the concepts were very easy to understand and follow. It feels that the lecturer prepares very well the topics.» (Very good)
- Projekten är väldigt bra ur lärandesynpunkt men de tar bort focus på det viktiga momentet att sitta och göra uppgifter, läsa, tänka i boken och klura. Eftersom projektet oftast tar upp ALL tid finns ingen tid att själv få vara nyfiken och lära sig. 90 % av tiden med projektet handlar om att lösa programerings detaljer i matlab, 10 % om att lära sig ämnet. Jag tycker det fortf. ska finnas ett projekt och över lag är det ett bra sätt att lära sig på men just nu är det för stor fokus på projektet. Varför inte ha veckobaserade inlämningar som kan göras i grupp eller individuellt. » (Very good)
- this was a really informative one...» (Very good)

13. What should definitely be changed in the course?

- Add review lectures also in the middle of the course .»
- I hope at the end of each lecture, teacher can offer a summarize about what we discussed today. It may make us more clearly!»
- I think that the team work is not working well. A good way to check the progress of such soft skill is having one meeting at the beginning with each team to discuss the project, and if necessary assign a coordinator within the group. »
- Maybe you could ask students to participate more in exercise sessions giving them to do the resolution of problems during the session (One student might go to solve it on the blackboard, or something like that). Another thing that can be changed is the text book.»
- type of exercises.»
- no comments»
- Although this is a matter of personal interest regarding my own Master"s programme, I would like to have more content in cell systems and the different kinds of fading and when they can be applicable, and maybe less on signal processing. Given that formulas such as the BER for different modulations have to be taken in the formula sheet at the exam, my suggestion would be either to allow the students to carry more notes (maybe one or two extra pages) or to provide these formulae at the exam. »
- No»
- the quizes should be less tricky»
- not having exercises 8am on monday morning»
- the early exercise-sessions at 8am!»
- More clear and consistent notation, more experimental work, maybe some lab work instead of one of the projects?»
- Maybe arrange the quiz time in the afternoon. Because 8:00a.m. is too early.»
- Final exam should be a little more in harmony with the time and the level of exercises offered. This course need a considerable of solved exercises preferably exam exercises for the sake of education. It is truly lacking in this course. »
- none»
- the project 2»
- Quize time should change. »
- just one thing, shift the quizzes from exercise session to lecture time. »
- Exercises from the text book. Include more conceptual questions. Examination questions are really nice and those kind of questions should be included into the exercise sections.»
- Can we add some topics in state-of-art for wireless communication? »
- The exam requires too many formulas to remember or fit in the paper. Some formulas should be provided.»
- Focused more on the concept, rather than the formulas»
- Workload is too much. Maybe cellular systems can be omitted from the context. I think they are not hard to learn by yourself. In addition, quizzes must scheduled in the afternoon.»

14. What should definitely not be changed in the course?

- Project 2»
- The projects, it makes me understand more deeply about frequency selective channel. It"s nice to do this project.»
- Reviews Slides The coordination between the projects of the other lecture. »
- Quizzes.»
- Projects and the textbook.»

- Quiz, two projects and same deadlines, lecture slides and timings. Thanks to Erik and TAs.»
- All is OK.»
