ABSTRACT:
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: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.
