Synopsis:

The core parts of the course cover the parameter estimation and optimal filtration theory and the feed-back systems theory. The theoretical results are applied on the design of synchronizers, equalizers and channel state estimators for digital communication systems. The course also covers the synchronization and equalization for spatial diversity systems and active interference cancellation methods in multiuser systems. The seminars are focused on practical algorithm design using computer simulation.
