A code division multiple access receiver, which receives a signal combining both information signals and training signals, has an interference canceler that successively estimates and cancels interference caused by the training signals. The interference canceler also successively estimates and cancels interference caused by the information signals. The estimating and canceling process is preferably repeated, for each training signal and each information signal, in two or more stages.
Un récepteur à accès multiple par répartition de code, qui reçoit un signal combinant des signaux d'information et des signaux d'apprentissage, est doté d'un suppresseur de brouillage qui tour à tour estime et annule le brouillage causé par les signaux d'apprentissage. En outre, le suppresseur de brouillage estime et annule tour à tour le brouillage causé par les signaux d'information.
