A received signal having multiple code channels is processed by filtering an error signal based on a difference between a received signal and an estimated received signal. The received signal is processed to recover data on each of the code channels and to generate an estimate of a transmitted signal corresponding to the received signal. A channel estimate is applied to the resulting estimated transmitted signal to generate the estimated received signal. After filtering of an error signal based on a difference between a received signal and an estimated received signal, a combiner combines the filtered error signal and the estimated transmitted signal.
Un égaliseur à décision rétroactive (DFE) traite un signal présentant des voies de codes multiples par filtrage d'un signal d'erreur reposant sur une différence entre un signal reçu et un signal reçu estimé. Le signal reçu est traité pour récupérer les données sur chacune des voies de codes et pour produire une estimation d'un signal transmis correspondant au signal reçu. Une estimation de voie est appliquée au signal transmis estimé résultant pour obtenir le signal reçu estimé. Une fois que le filtre a filtré le signal d'erreur, un combineur combine le signal d'erreur filtré ainsi que le signal transmis estimé.
