Schedule for Wed and Fri


I see that most of the class has signed up for a presentation slot on Wed or Fri. Just a few tips to organize your presentations.

  • Please prepare 4-5 slides for your presentation and send them to me as either a pdf or a ppt at least a few hours before your scheduled time-slot, so that I can have all your slides ready before the class.
  • Do not waste time preparing fancy slides – just brief descriptions, screenshots and pictures showing what you did, what worked and what didn’t.
  • Your final project reports are due on Friday. If you would like more time to turn this in, let me know. Again do not waste time on preparing fancy pictures etc. Your earlier lab reports are a good template for this. Please talk to Mahboob or myself if you are unsure about the appropriate level of detail.
  • This last part is optional, but I’d ideally like along with your project report a zip file containing GNU-radio flowgraphs, scripts, FPGA code and anything else that you wrote or designed for the project that will allow us to reproduce your work. This way, we will be able to build on your work at some later date.

Use the below space for any questions or suggestions.


Mahboob’s thesis defense and practice talk


You should have received Mahboob’s email about his upcoming thesis defense and practice talks scheduled for Wed and Mon respectively.

I’d encourage you to attend if you’d like to learn a bit about some state-of-the-art topics in wireless. While you will not be able to understand his talk in every detail based only on what we have done in class this semester, the broad outlines of his work should be intelligible.

Please feel free to participate actively with questions and comments – especially if you attend his practice talk on Mon; it will help Mahboob improve the clarity of his presentation and generally make things more lively and fun.

Presentation opportunity at Iowa City business group event


The Iowa City Area Development (ICAD) Group is hosting a reception next Friday and our class has been offered the opportunity to do a demo or a poster at this event. This could be a good networking opportunity or simply a fun way of showing off the work you are doing for your class project.

If you are interested in participating in this event, please send me an email. You can, if you wish, opt out of doing a project presentation in class if you are selected to present at the ICAD event.

Details on the reception are here.

On May 10, 2013, ICAD Group is providing its investors, partners and the community a unique opportunity to see firsthand how engineering is shaping the future of business in Iowa’s Creative Corridor.

Working with the University of Iowa College of Engineering, the University of Iowa Alumni Association and local high schools, ICAD Group is hosting a three hour open house and networking reception focusing on the importance of STEM education (science, technology, engineering and mathematics) and the workforce challenges faced by local employers.

The event will be held from 3:00 p.m. – 6:00 p.m. Friday, May 10, 2013, in the Amos Dean Ballroom at the Sheraton Iowa City Hotel.  Hors d’oeuvres and beverages will be provided.  The event is free, but registration is required at

Class project presentations sign-up


As discussed in class yesterday, we will not have any further lectures for the class.

Instead, Mahboob and I will be available in class on Wed, Fri and Mon (May 1, 3, 6) for one-on-one discussion with everyone in the class on the plans and progress on the projects.

We need to meet with every group at least once between now and Monday. We should meet as early as possible if you have any questions at all on how to get started on your project – either in class tomorrow (Wed) or by appointment.

Your final project report (which can simply be your initial proposal which you submitted yesterday updated) will be due on class on Fri (May 10). We will also have short presentations from each group on Wed and Fri next week.

Class projects schedule


After our Lab 7(b) reports that were due yesterday, we have no further Homeworks, Exams or other requirements for the class except for the project, so I hope we can spend all our energies for the remaining 2.5 weeks of the semester on this.

That being said, you are always welcome to turn in bonus Homework problems and Lab exercises at any time until the last week of classes for extra credit.

This post is a follow-up on my earlier list of suggestions for projects. We will discuss each of these suggested projects (along with any others you’d like to add) in the coming lectures. I hope this will also be a fun way to see how the ideas we have been exploring in the labs apply to wireless comms design problems.

Here’s a proposed timeline for the projects from now through the end of the semester.

  • Apr 22-29. Discuss and pick a topic for your project. These can be either individual or 2-person team projects. If you want to work as 3-person or larger team, we can discuss it if there is a good justification.
  • Apr 29. Write a short description of your project. This description should not be more than 1 page long and should consist of (a) a clearly stated goal, (b) motivation i.e. why this is useful or interesting and how it relates to the subject of this class, (c) a block diagram showing your proposed design with an explanation, and (d) expected outcome i.e. what you will demo or deliver in 2 weeks time. Be sure to clearly identify any hardware or software you need in addition to what we have in our lab.
  • Apr 29-May 7. Implement your design.
  • May 8-10. In class demo or short presentation.
  • May 10. Final deliverable will include an updated project description (the same one that you will have submitted on Apr 29) documenting what worked and what didn’t along with all source-code, scripts and MATLAB simulation code.

Time is short, so you should get started on this ASAP. Please pick a topic by Thursday or so and make an appointment to speak with Mahboob to make sure your proposed project is reasonable and realistic.

The project will be mostly graded on effort, so it is ok if you are unsuccessful. We only require a good faith effort. Specifically, we expect that you put in about 15 hours or so on this over the next 2.5 weeks including all the reading, writing, design and lab work.

Please post your questions, comments or suggestions in comments below. I hope this will be both fun and a good learning experience.

Course survey, HW 3, Quiz 2 and Lab 7


Just a reminder that we are having a flurry of activities this week relating to this class.

  • Course evaluation survey. You must have received an email with a link to this survey in your Hawkmail inbox sometime in the last week or so. If you have not received this email, please let me know or contact CSS yourself immediately.
  • PLEASE TAKE THE SURVEY! I know the survey is a pain, but it does matter. Especially for a 195 class, which is a non-regular offering. Especially for this class, which is an experimental class, being offered for the first time etc.
  • We are meeting in the lab on Mon, Apr 15 to continue our Lab 7(b) from Fri. This lab is in many ways a culmination of everything we have done this semester and I also think it is fun, so please take the time to understand it well.
  • We have HW 3 due in class on Friday. Lab 7(b) reports are also due on Friday (by email to Mahboob). Finally, we will also have our second Quiz in class on Friday. With this all our formal requirements for the class will be done except the class project. Bonus exercises have no due dates and you can continue to do those until the end of the semester.
  • And I don’t know if I mentioned this earlier, but please take the course survey!


Lab # 7 (b): Studying synchronization loops in BPSK systems

The manual for lab 7(b) is now posted on ICON. Please bring it with you when you come to the lab today.
