If there is something to be announced, it will be published here...
Course Outline
The course teaches the fundamentals of digital communication systems. The main topics are analog and digital modulation, signals and linear time-invariant systems, baseband and passband transmission, continuous-time and discrete-time channel models, noise and signal-to-noise ratio (SNR), detection theory, inter-symbol interference and orthogonal frequency-division multiplexing (OFDM), basics of forward error correction, basics of information theory, multiple-access protocols, and spread-spectrum modulation.
The exercises cover theoretical aspects as well as modeling of simple communication systems in GNU Octave.
