Space-time block-coding (STBC) with multiple streams in orhogonal frequency division mulitplexing (OFDM) for wireless local area networks (WLAN) and error metrics for soft decision with channel information

摘要

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