Abstract:
1. An iterative decoding and equalizing device for high bit rate communication over frequency-selective channels with multiple transmit and receive antennas, said device comprising: a decision feedback equalizer adapted to receive data from different receive antennas and including: a subtractor for subtracting an output of the recursive backward filter from an output of the forward filter to output subtracted data, wherein the subtracted data is fed to decision means along with the output of the channel decoder, wherein the decision means produce a statistic which is forwarded to the channel decoder, wherein the decision means take into account space noise correlation at the subtracted data of the subtractor, wherein the decision means and the channel decoder are separated by space-time de-interleaving at a binary level, and wherein the forward filter and the recursive backward filter are iteratively adapted minimizing a mean square error at the output of the subtraction means.
