Résumé : This thesis deals with multiuser detection for spectrally-efficient wireless communication systems. The aim of this work is to propose new advanced low-complexity multiuser receivers with near-optimal detection performance. We consider frequency division multiplexing satellite systems where each user employs a continuous phase modulation, serially concatenated with an outer code through an interleaver, and iterative detection/decoding. We also consider linear channels impaired by additive white Gaussian noise, focusing on frequency division multiplexing systems where adjacent channels are allowed to overlap in frequency, and on code division multiple access systems. For the considred scenarios, we propose detection schemes with an excellent performance/complexity tradeoff which allow us to implement transmission schemes with unprecedented spectral efficiency at a price of a limited complexity increase with respect to a classical single-user receiver which neglects the interference.

Mots-clés : multiuser detection, iterative detection and decoding, frequency division multiplexing systems, continuous phase modulation
