A method for reducing interference in a MIMO MultiCode MC-CDMA system is disclosed wherein a BLAST algorithm is implemented over one block of correlation reception data yand estimation channel values H of the correlation reception data yto generate a group of temporary decision symbols C. One symbol, C, is selected having a maximum SNR value from the temporary decision symbols. The temporary decision symbols, C, other than the selected symbol, C, are combined with the estimated channel value H to recover a group of temporary interference signals over the selected symbol, C. The interference signals are subtracted from the correlation reception signal vector, yto generate a corrected reception signal vector y, and a more accurate decision symbol Cis identified from the corrected reception signal vector yand original estimation channel values. The foregoing steps are repeated for other symbols C.
