The embodiments of the present application relate to the field of communications, and provide a signal distortion pre-correction method, a signal distortion pre-correction device, and a non-volatile storage medium. In the present application, the mutual coupling filtering parameters and the predistortion coefficient candidate set are obtained by training the feedback signal collected by the multi-channel coupling element, so that the mutual coupling filtering processing can be performed on the forward signal of the digital channel according to the obtained mutual coupling filtering parameter, to make the target predistortion coefficient selected in the predistortion coefficient candidate set according to the forward signal after mutual coupling filtering and the forward signal of the digital channel to be processed to be the predistortion coefficient considering the mutual coupling factor of the digital channel.

Signal distortion pre-correction method, device and non-volatile storage medium

An antenna array decoupling method, apparatus and system, and a non-transitory computer-readable storage medium are disclosed. The method may include: receiving predetermined digital domain signals of a plurality of channels, each of the plurality of channels being a data channel corresponding to a respective one of array elements in an antenna array 5 (S); determining decoupling factors of channels involved in decoupling corresponding to each channel, the decoupling factors being factors which have been solved for beforehand according to measured in-array pattern information of each array element in the antenna array (S); and processing the predetermined digital domain signals of the channels involved in decoupling corresponding to each channel according to the decoupling factors to obtain a 10 decoupled predetermined digital domain signal of each channel (S).
