Access point with simultaneous downlink transmission of independent data for multiple client stations

摘要

A wireless network device includes modulation modules, each configured to receive a data stream and modulate the data stream to generate a modulated data stream. A matrix module generates a multiplexing matrix based on channel conditions between the wireless network device and each of a plurality of client stations, and applies the multiplexing matrix to each of the modulated data streams to generate multiplexed data streams. The wireless network device also includes summing modules, each configured to sum at least two of the multiplexed data streams to generate a transmit data stream. A first transmitter transmits a first one of the transmit data streams during a downlink transmission period to a first one of the client stations. A second transmitter transmits a second one of the transmit data streams to a second one of the client stations while the first transmitter transmits the first one of the transmit data streams.
