Spectral Analysis of Signals, Fall 2006

For information about the location and time of the lectures and labs, please go
here.

To provide the student with the knowledge necessary to think in the "frequency domain" and to introduce the state-of-the-art methods and algorithms for computer-aided spectral analysis of temporal and spatial signals with applications in communications, signal analysis, radar systems, emitter location, signal recognition, and others.

(For information on the old/new book, see Literature below.)

The solutions should be put in the postbox marked Inlämningsuppgifter SA06 on floor 2 in house 2.

The results will be continously updated on this page.

For some general advice on the presentation etc of the homework assignments, please check this page.

Since the examination is based on the homeworks, discussing the solutions to the homework assignments with your colleagues or anybody else is strictly forbidden. Note that in grading the homework solutions we will put an emphasis on your interpretations of the results. Also, note that the deadlines are strict! This means that a homework which is handed in late may receive no points at all.

(For information on the old/new book, see Literature below.)

For your progress so far, please check this page.

The computer-labs are mandatory. If you for some reason cannot attend a specific session, please, contact the person responsible for the lab well in advance. If your absence was not predicted, make this contact as soon as possible. Make sure that you come prepared (see the course syllabus) for descriptions of the different lab sessions).

All computer labs are scheduled to be in room 2315 (house 2, 3rd floor) at Pollacksbacken.

IMPORTANT: For access to the PC-labs at the department, an account at UpUnet-S (the university computer network for students) is required. When logging in password C should be used! Make sure that you have this password! Information about UpUnet-S can be found at http://www.student.uu.se/upunets/.

From the computer labs at the IT-department you can access matlab scripts for all the labs (so you don't have to do any programming yourself). Those lab-files can be found in two ways. If you have a G: drive mounted when you log into the system you find the files under G:\Program\Systemteknik\Spektralanalys\. If you don't have G: mounted you can either mount it yourself (using "Map Network Drive") or you can find the files directly under "My Network Places"-"Entire Network"-"Microsoft Windows Network"-"It-Pclab"\Pegasus\Program\Systemteknik\Spektralanalys.

The students are required to pass all five labs. The exam consists of solving the five homework assignments. Each homework assignment gives a maximum of 20 points. The points required for the different grades are as follows.

For Master of Science students:

For PhD students:

During the last lecture, up to 4 students may choose to present some applications of spectral analysis. Each presentation will last 25 minutes (including discussion) and its topic can be selected by the student or suggested by us. For each presentation a maximum of 20 points can be awarded.
