Abstract
A method for beamforming in a communication system includes receiving a plurality of signals via a plurality of antennas, where the plurality of signals corresponds to at least one known training signal, generating a respective one of a plurality of different antenna weight vectors to be applied to the plurality of antennas as each of the plurality of signals is received, where each of the plurality of antenna weight vectors is a respective base vector of a unitary matrix, and generating a receiver antenna weight vector based on at least the received plurality of signals, the plurality of different antenna weight vectors, and the at least one known training signal.
