Abstract: A method and apparatus for controlling an antenna array for wireless communication are described. The method is applied at a receiver and it uses a least squares algorithm for recovering the spatial signature of each of a plurality of signals transmitted simultaneously by a plurality of transmitters. The spatial signature is used for controlling the antenna array in order to achieve directional reception in a wireless communication system and suppress co-channel interference. The method can be used either in single transmitter configurations for smart antenna reception or multi-transmitter configurations for space-division multiple access systems. Furthermore, it can be used in conjunction with multi-carrier modulation signaling.
