Abstract: 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.

Abstract: Embodiments of the present invention disclose a signal processing method, apparatus, and system, where the method includes: receiving a downlink signal that carries an uplink signal; and performing first interference cancellation on the uplink signal by using an estimated self-interference signal, so that a remaining amount of interference of the uplink signal is less than a first interference threshold, thereby minimizing out-of-band interference of the uplink signal on the downlink signal without using a plurality of radio frequency front-ends or without using a duplexer on a same radio frequency front-end. In the embodiments of the present invention, no duplexer is adopted, and therefore, difficulty and a cost of base station and system layout can be reduced, and extra energy consumption of a mobile terminal can also be reduced.

Abstract: Embodiments of the present invention relate to a method and an apparatus for processing signal interference, including: splitting a first self-interference signal into at least two same sub self-interference signals, adjusting amplitudes and phases of the sub self-interference signals to obtain adjusted sub-signals, superposing the adjusted sub-signals and received signals, to obtain superposed sub-signals, filtering the superposed sub-signals by using filters of corresponding channels, to obtain wanted sub-signals, and merging each of the wanted sub-signals to obtain a complete wanted signal. Because received signals are separately filtered by using n different channels, it can be implemented that a self-interference signal can be effectively filtered out on each frequency band.
