Adaptive interference suppression method and system based on multiple reference signals

The invention provides a self-adaptive interference suppression method and system based on multiple reference signals, and belongs to the technical field of communication. The method comprises the steps that multiple reference signals are obtained, the multiple reference signals comprise a reference signal obtained after a transmitting signal and a radio frequency signal pass through a feedback channel and a reference signal formed by the transmitting signal and a conjugate signal of the transmitting signal, the multiple reference signals are filtered based on an adaptive filter, and a reconstructed self-interference signal is obtained; on the basis of the reconstructed self-interference signal, interference suppression is carried out on a receiving signal received by a receiving end baseband of the home terminal equipment, and a nonlinear self-interference signal in a communication link can be effectively eliminated. According to the invention, the digital domain self-interference cancellation capability is
