Transmit beamforming and receive combining can be simply implemented over frequency selective channels by using multiple-input multiple-output (MIMO) technology combined with orthogonal frequency division multiplexing (OFDM) in what is known as MIMO-OFDM. Generally this requires knowledge of the transmit beamforming vectors for every tone at the transmitter… CONTINUE READING
