摘要： A system enhances communications security in a wireless local area network (WLAN). The system includes a multiple antenna array arranged to transmit and receive signals; and a transmitter/receiver coupled to the multiple antenna array and configured to transmit and receive the signals. The transmitter/receiver includes a beamformer, which in turn includes a signal processor component that generates a signal beam for transmission to an intended user, and a blinding component that computes one or more blinding beams using only channel state information of the intended user. The blinding beams have a zero inter-user interference condition with the signal beam. The transmitter/receiver transmits the signal beam and the blinding beams simultaneously
