MIMO (multiple in multiple out) antenna system draw attention in the recent years due to its potential for achieving high data rates. In this work novel DSP algorithm and FPGA implementation will be presented that allows transmitting M data streams to M receiving antennas from N transmitting antennas (M ≤ N) into the same frequency with total interference suppression while maximizing channel gain for each data stream at the same time.
