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.
