1. A method of receiving data over M receiving antennas from N transmitting antennas, where M and N are integers, the method comprising the steps of:
- receiving M signals over the M receiving antennas;
applying the M signals to a space/time decoder;
determining noise powers for M channels, with the M channels being based on the M signals;
applying Viterbi filtering to the M channels utilizing the noise powers; and
deriving received data from the filtered M channels.
