Abstract: A method for channel smoothing with transmit beamforming includes transmitting, by a first device, a non-data-packet (NDP) frame to a second device. The method also includes receiving, by the second device, the NDP frame and transmitting a compressed report to the first device. The method further includes receiving, by the first device, the compressed report and deriving a first beamforming matrix from the compressed report. A second beamforming matrix is generated employing a processing known to the second device, and a data frame is transmitted to the second device using the second beamforming matrix.

Abstract: An OFDM receiver comprises a (FEC) decoder and a nonlinearity compensation circuit. The nonlinearity compensation circuit is operable to generate estimates of constellation points transmitted on each of a plurality of subcarriers of a received signal based on soft decisions from the FEC decoder and based on a model of nonlinear distortion introduced by a transmitter from which the received signal was received. The generation of the estimates may be based on a measure of distance between a function of the received signal and a synthesized version of the received signal. The generation of the estimates may comprise iterative processing of symbols of the received signal, and the iterative processing may comprise a plurality of outer iterations and a plurality of inner iterations.

Abstract: An orthogonal frequency division multiple Access (OFDMA) receiver may comprise a forward error correction (FEC) decoder and nonlinearity compensation circuitry. The OFDMA receiver may be configured to receive a signal that is a result of multiple concurrent, partially synchronized transmissions from multiple transmitters using different subsets of subcarriers. The nonlinearity compensation circuit may be operable to generate estimates of constellation points transmitted on each of a plurality of the subcarriers of the received signal. The generation of the estimates may be based on soft decisions from the FEC decoder, and models of nonlinear distortion introduced by the multiple transmitters.
