Turbo-égalisation des modulations MAQ-M sur canaux non stationnaires sélectifs en fréquences

This paper deals with a new receiver scheme, labelled turbo-equalizer , suited for transmissions over fading and noisy channel using M-QAM modulation. Adaptive equalization and channel decoding are jointly used through an iterative process. By means of a principle borrowed from turbo-codes, the turbo-equalizer can totally overcome ISI. Results are presented for 4-QAM and 16- QAM modulation.
