Teil: Zusammenfassung der Ergebnisse,e where one channel use involves sending signals simultaneously through several propagation paths. The use of multiple transmit and receive antennas allows one to reach capacities that cannot be obtained with any other technique using present-day technology, and is expected to make it possible to in

,Tour d’horizon,st present coding in the signal space, and the techniques used for decoding. Next, we highlight the basic differences between the additive white Gaussian noise channel and different models of fading channels. The performance bounds following Shannon’s results are described, along with the historical development of coding theory.

Channel models for digital transmission,The aim of this chapter is to examine in some detail the problem of constructing models for the channels to be used for digital transmission. The emphasis here is on wireless channels. and special attention will be paid to modeling of fading. The impact of the model on the performance assessment of a coded transmission system is also discussed.

Coding in a signal space,lations whose elements are n-tuples of “elementary signals” chosen in a set X. We evaluate the error probability obtained when a code in a signal space is used for transmission over the additive while Gaussian noise channel. Constellalions are then compared on the basis of their bandwidth and power
