The invention relates to a reception method for communication over frequency-selective channels with a plurality of send antennas and a plurality of receive antennas, to process data received by the receive antennas that, on sending, was successively modulated and spread. To this end, reception uses: n first linear filtering ( 202, 202 ′); first interference subtraction ( 201 ) that uses an estimate of previously regenerated multi-antenna interference (MAI) and intersymbol interference (ISI); second linear filtering ( 205, 205 ′); second interference subtraction ( 204 ) that uses an estimate of previously regenerated multi-user interference (MUI); processing to generate an MAI+ISI interference estimate and an MUI interference estimate for the received data from the data filtered in this way. The invention relates further to a reception system adapted to implement the method and a transmission system including the reception system. |
