Special Announcements

  • Please make sure that you have registered for the course on IS-Academia so that you can access the lecture notes on Nota Bene.
  • You can find a tutorial video on how to use Nota Bene here
  • If you want a printed copy of the textbook, please send an email to mani.bastaniparizi@epfl.ch
  • Your midterm quiz will take place on Friday, April 17, 2015.
  • The average and the standard deviation of your midterm grades are 15.09 and 6.94 respectively. Here you can find a histogram of the grades.
  • Your final exam will take place on Monday, June 22, 2015 at 12:15 in room CO2. You are allowed to have one handwritten A4 page of summary (double-sided) with you for the exam.

Project

  • Please find instructions about your final project here.
  • You should register your groups at latest by Wednesday April 29.
  • You will present your projects on Friday May 29.
  • Here is some more information (based on the frequently asked questions) about your project:
    • On the presentation day (Friday, May 29), you will run your projects on your own laptops (in Airplane Mode). However, you should send us your codes (by a deadline just before the presentation session that we will announce later).
    • You cannot use external speaker at the transmitter but you may use an external microphone for the receiver if you wish.
    • The text file that you will be asked to transmit will contain roughly 150 characters.
    • Each group will have 5 minutes in total to present their project during which they first have to explain their signaling scheme briefly in about 2 minutes. The remaining time (2 to 3 minutes) is for transmitting the text file (that will be given to you on-the-spot).
    • As we have already mentioned, you don’t need to implement a real-time decoder. You can record and store the transmitted signal and decode it afterwards. Furthermore, you don’t need to communicate the length of the data to be transmitted to the receiver. You can manually start and stop recording at the receiver side.
