Abstract: A multicarrier transceiver for communicating spatially multiplexed orthogonal frequency division multiplexed (OFDM) signals over two or more spatial channels in a wireless access network in accordance with an orthogonal frequency division multiple access technique with a plurality of antennas is generally disclosed herein. In some embodiments, the multicarrier transceiver comprises a matrix generator to generate a matrix for precoding transmission symbols based an indicator received from a receiving station, the indicator being based at least in part on channel characteristics. The multicarrier transceiver also includes a precoder to multiply the transmission symbols by the matrix for transmission on groups of subcarriers that comprise the OFDM signals using the antennas for transmission through two or more spatial channels, each of the two or more spatial channels to concurrently convey separate spatially multiplexed data streams over a same set of subcarriers.

Abstract: A communication node of a wireless local area network utilizes a multi-element array antenna to estimate an angle-of-arrival for one or more signal sources which may communicate on symbol-modulated orthogonal subcarriers. Channel coefficients may be estimated from the angle-of-arrival for the one or more signal sources to increase channel capacity, improve channel equalization and reduce the effects of multipath fading. Beamforming based on the angle-of-arrival may also be performed for directional reception and/or transmission of communications with the one or more signal sources.

Abstract: A DOA estimation unit is provided with at least one of two DOA estimation techniques to determine the DOA of signals wireless transmitted. A first technique includes determination of the DOA based at least in part on a relationship between a received signal vector and a number of signal directional vectors. The second technique includes determination of the DOAs of the L multipaths of a signal by searching in a direction range centered on a determined DOA of the signal.
