Course Aim
The student should be able to
- Describe properties of communication systems both in time and frequency
- Describe linear modulation techniques such as PAM, PSK, QAM and FSK in terms of geometry
- Derive optimal receiver for the Gaussian channel
- Derive optimal and linear equalizers for the dispersive channel
- Analyze and simulate the performance (in terms of bitrate, bit error probabilities, and bandwidth).

The course treat the following topics:
- Concepts such as bit rate, bandwidth, and bit error probabilitiy
- Linear modulation (PAM, QAM, PSK, FSK)
- Geometrical representation
- Signaling over the additive Gaussian noise (AWGN) channel
- Optimal receivers and error analysis for the AWGN Channel
- Signaling over dispersive channels
- Receivers and equalizers for the dispersive channel (both linear and non-linear)

To be able to simulate digital communications systems is very important in todays designs. The laborations, where the students themselves build simulation chains, is therefore a central part the course.

Lectures, problem solving sessions, and take home labs.

Normally examined by a written exam with marks U,3,4,5, and approved labs. Oral examination can be used.

The course will not be given every year.
