<p>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 y<SUP>i</SUP> and estimation channel values H of the correlation reception data y<SUP>i</SUP> to generate a group of temporary decision symbols C . One symbol, (I) , is selected having a maximum SNR value from the temporary decision symbols. The temporary decision symbols, C , other than the selected symbol, (I) , are combined with the estimated channel value H to recover a group of temporary interference signals over the selected symbol, (I) . The interference signals are subtracted from the correlation reception signal vector, y' to generate a corrected reception signal vector y <SUP>i+1</SUP> , and a more accurate decision symbol (II)+l is identified from the corrected reception signal vector y <SUP>i+1</SUP> and original estimation channel values. The foregoing steps are repeated for other symbols (I).</p> |
