摘要： A method for reducing adjacent-channel interference includes: obtaining, by a receiver, a first analog signal from a radio frequency front-end of a transmitter, where the first analog signal is a signal transmitted by the transmitter to the outside, and the signal transmitted by the transmitter to the outside forms a self-interference signal at an antenna of the receiver; performing analog-to-digital conversion on the first analog signal so as to obtain a first digital signal; receiving, by the receiver, a second analog signal, where the second analog signal includes a wanted signal and the self-interference signal; performing analog-to-digital conversion on the second analog signal so as to obtain a second digital signal; and performing digital cancellation on the second digital signal and the first digital signal so as to obtain a wanted digital signal of the second digital signal. According to the present invention, adjacent-channel interference from signal transmitting to signal receiving is reduced in a signal processing manner. There is no need to increase an installation distance between transmit and receive antennas, and adjacent frequency bands may be configured for a backhaul link and an access link so as to improve configuration flexibility of the backhaul link and the access link.
