METHOD, APPARATUS, AND SYSTEM FOR PROCESSING INTERFERENCE SIGNAL

摘要

Embodiments of the present invention provide a method, an apparatus, and a system for processing an interference signal, so as to eliminate an interference signal in a full duplex multi-antenna system. The method includes: receiving a radio signal, where the signal includes a self-interference signal of a transmit antenna, and the self-interference signal includes a first self-interference signal, and a second self-interference signal; performing primary interference cancellation processing, by using a first reference signal, on the received signal to eliminate the first self-interference signal; and performing secondary interference cancellation processing, by using a second reference signal, on the signal after the primary interference cancellation processing to eliminate the second self-interference signal.

1. A method for processing an interference signal, the method comprising:
receiving a radio signal comprising a self-interference signal of a transmit antenna, the self-interference signal comprises a first self-interference signal and a second self-interference signal, power of the first self-interference signal is greater than a first power threshold, a time delay of the first self-interference signal is less than a first time delay threshold, power of the second self-interference signal is less than the first power threshold and greater than a second power threshold, and a time delay of the second self-interference signal is greater than the first time delay threshold and less than a second time delay threshold; performing primary interference cancellation processing, by using a first reference signal, on the received signal to eliminate the first self-interference signal, wherein the first reference signal is obtained by coupling a local transmit signal; and performing secondary interference cancellation processing, by using a second reference signal, on the signal after the primary interference cancellation processing to eliminate the second self-interference signal, wherein the second reference signal is obtained by coupling a local transmit signal.
