Abstract
A multiple-input multiple output (MIMO) receiver includes circuitry to receive a MIMO transmission through a plurality of antennas over a channel comprising two or more 20 MHz portions of bandwidth. The MIMO transmission comprises a plurality of streams, each transmitted over a corresponding spatial channel and configured for reception by multiple user stations. The MIMO receiver also includes circuitry to simultaneously accumulate signal information within at least two or more of the 20 MHz portions of bandwidth. Each 20 MHz portion comprises a plurality of OFDM subcarriers. The MIMO receiver also includes circuitry to demodulate at least one of the steams using receive beamforming techniques. In this way, multi-user protocol data units can be received.
