Abstract:
1. A multiple-input multiple output (MIMO) receiver comprising: 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 comprising a plurality of streams, each transmitted over a corresponding spatial channel and configured for reception by multiple user stations; a plurality of subchannel filters operating in parallel to separately accumulate signal information within two or more of the 20MHz portions of bandwidth, each subchannel filter to accumulate signal information within one of the 20 MHz portions of bandwidth, each 20 MHz portion comprising a plurality of OFDM subcarriers; and circuitry to perform an FFT on digital signals generated by the subchannel filters to demodulate OFDM symbols associated with at least one of the steams, wherein receiving the MIMO transmission includes performing receive beamforming techniques to extract information from the spatial channels.
