(English) Signal Processing in Telecommunications and Radar course
summer 2007/8

Current issues

Currently lectures are scheduled on Thu, 8:15-10. There is a student proposal to make Thu free of any courses, so we consider changing to Tue, 10:15-12 (there is some room, as the satellite course drifted elsewhere). If all the students agree, I am not against. We will decide next Thu.

Teachers

A person responsible for the whole course is me, Jacek Misiurewicz (room 447, tel 7478). The team consists also of dr. Krzysztof Kulpa (r. 447) and mgr Mateusz Malanowski (r. 453), who will have part of lectures and will supervise part of projects.

Projects

A three-stage project is to be done during the semester. See the schedule to find the deadlines of stages. Project hours (to be defined) are reserved for individual discussion - according to student's needs, and for project stage submission - according to schedule.

Project stages

Stage 1 - Projects specification: describe (on a single page) what you're going to do; find a title; declare minimal goal and possible extension; decide type of work (simulation procedures? working model? study of ...?) specify tools (Octave? Matlab? C++? Parts of code taken from existing libraries?) and final product (command-line? GUI? interactive webpage? results in a nice plot or a table?)
Stage 2 - Algorithm specification: describe details and theoretical background of algorithms forming the base of your work; denote exactly what will be taken from libraries, and what you're going to code by yourself.
Stage 3 - Final project: present a working program and results of simulations; submit a user manual for the program and written description of simulation results (paper) and program code (CD).
Stage 3 submission will require:
- Few pages of documentation/report on paper, printed (or handwritten) by a student (two-sided if possible). It should document the usage of your code (e.g. "help" for the student written m-files/c-functions/etc.) and show the results (e. g. plot of BER vs. SNR, and/or an example of error in a specific situation, or the signal before and after some filtering etc.).
  There is no need to repeat the parts that formed P1 or P2 if they haven't changed.
- Your code archived on a CD/floppy or zip'ped on a USB drive (yes, I'll return the drive after copying ;-) ); instead it can be printed on paper - but only if it is not more than 1 page;
- A show (approx. 6 minutes if you are prepared) of your program in action. Prepare yourself for a quick show - setup everything on your laptop (or a borrowed one ;-) ) so it works well. Be prepared for some questions ("Please show what is happening if we change the SNR/sampling rate/number of channels/whatever") or discussion ("why is the plot so strange?" "show how the decoding is implemented in your m-file"), sometimes even quick patch to be done on spot ("Please try to use a pre-filter and compare the results - it's 3 lines of code, and should work much better").

When submitting the Stage 2 or 3 you may change some specifications, but the change must be justified in writing.

Project themes

Each student should define her/his own project theme. It must include type of work, investigated effect, type of component under investigation and target application. The tools may be specified in the title or in the description. Below you may find examples of theme parts.

(type of work)

Simulation of...
Experimental model of...
A tool for...
A study of...
A plugin for ... doing ....

(effect)

...noise effects in...
...nonlinear effects in...
...multipath effects in...
...Doppler effects in...
...influence of number of bits on...
...practical application of...

(part of a system)

...transmission channel...
...directional reception...
...matched/correlation filtering...
...modulation/demodulation...
...coding/decoding with _______ method...
...echo cancellation...

(application area)

for a /voice telephony/digital video broadcast/GSM/UMTS/WiFi/Bluetooth/etc.
for a /pulsed/continuous wave/noise/passive/etc. radar/sonar type.

We strongly encourage to use these as an example to create your own project, e.g. connected with your chosen thesis area. If you have ANY doubt, please discuss the subject BEFORE the deadline of Stage 1.

Example themes:

Experimental model of software radio. (in the description: It will work off-line using simulated DAB or FM signals.)
Study of Doppler effect in UMTS communication.
A tool for multipath effect modelling in DAB.
Simulation of background noise level effect on sonar detector.

Tests

One test will be administered during the semester - see the schedule (Test 1).

A final exam is during the session (two dates will be scheduled). Additionally, an "exam0" date will be available to students with ((at least 50% from the test1) .AND. (at least 50% from the project)).

Paper, pen, pencil, ruler. No books etc.. Notes are allowed, providing they are prepared by a student himself, with hand writing (no photocopying!)
Only exception: lecture slide copies are allowed.

Books

The course is based on selected chapters of following books:

Lecture slides

A list of links to slides follows. If you see here some future lectures, just don't care. The only official version is the one seen in the lecture room ;-). However, you may expect the good version to show up here the evening before the lecture.

Some notes are presented on the blackboard. If you don't attend the lecture, you miss them.

Lecture 1:
Introduction Lecture 2:
superheterodyne
Image band
Nice dualband receiver example
Matched filter reception - dual receiver and one transmitter. The dual receiver is used for estimation of echo direction - we'll discuss it later.

Lecture 3:
balanced mixer (MOS)
balanced mixer (bipolar); note error in input markings
balanced mixer (diode bridge)
destructive multipath interference points (l2=distance vs. h=tower height), 7GHz, curves for [1 3 5 .. 15]*lambda/2, flat earth geometry

Lecture 7:
slides (pdf)
Easy conference paper with some equations (KKTOiUE conference, 1997)
Lecture 8: Happy Easter!

Lecture 9: Advanced radar
slides (pdf)

Lecture 10: Digital Radio
