ABSTRACT:
An apparatus and method for beamforming in a communication system are provided, in which a base station receives a channel vector from each of a plurality of mobile stations, generates an uplink channel matrix using the received channel vectors, generates a beamforming weight vector using the uplink channel matrix and a fixed constant that minimizes a channel error rate, and forms beams using the beamforming weight vector.
