Abstract

The invention discloses a signal processing method, a network device, a terminal and a computer-readable storage medium. The method comprises: acquiring a digital transmission signal sent by a transmission link and a digital reception signal received by a reception link; Digital receiving signal, constructing the nonlinear interference signal from the transmitting link to the receiving link; filtering out the nonlinear interference signal in the receiving link. The transceiver node of the present invention estimates the nonlinear interference signal transmitted by the transmission link and received and caused by the reception link according to the digital transmission signal transmitted in its own transmission link and the digital reception signal received in the reception link, And further delete the nonlinear interference signal in the receiving chain, so as to improve the multi-frequency working performance of the transmitting and receiving nodes, and improve the spectral efficiency of the system.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a signal processing method, network equipment, terminal and computer-readable storage medium. Background technique [0002] The field of mobile communication has experienced the development from the first generation to the fifth generation, and multi-band transmission has become a common phenomenon. From the fourth generation (4 th Generation, 4G) mobile communication system, introduced carrier aggregation (Carrier Aggregation, CA) or dual connectivity (Dual Connectivity, DC) technology that supports multi-band simultaneous operation, the fifth generation (5 th The 5G Non-StandAlone (NSA) method based on the joint networking of 4G and 5G air interfaces in the initial stage of the Generation (5G) mobile communication system has become the mainstream. When a wireless mobile communication device (base station or terminal) has multiple frequency bands to transmit ...
