ANTI-INTERFERENCE PROCESSING METHOD AND DEVICE FOR SIGNAL RECEPTION BASED ON MULTIPLE ANTENNAS

摘要

Embodiments of the present invention provide an anti-interference processing method and device for signal reception based on multiple antennas. The method comprises: receiving a mixed signal, the mixed signal comprising a wanted signal from a peer transmit antenna and a first interfering signal from a local transmit antenna; receiving a second interfering signal from the local transmit antenna; adjusting phase and amplitude of the second interfering signal, so that the second signal and the first interfering signal have the same phase and amplitude; and subtracting the adjusted second interfering signal from the mixed signal to obtain the wanted signal. In embodiments of the present invention, by adjusting the phase and amplitude of a local reference antenna and then performing interference cancellation, a local receive antenna can maintain a wanted signal from a transmit antenna at the peer end of communication, thereby achieving an effective interference cancellation performance without affecting the technology of space division multiple access with the receiving side at the peer end of communication based on transmit-antenna precoding.
