Abstract: 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 (S110); 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 (S120); 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 decoupled predetermined digital domain signal of each channel (S130).

Abstract: A device, method, and system for signal distortion pre-correction, and a composite system are disclosed. The device-includes: a signal distortion correction network module, a correction parameter trainer, a data collection module connected to an external power amplifier module, and a first conversion module. The data collection module is configured to perform time-division collection on output signals of channels of the power amplifier module and output analog feedback signals to the first conversion module. The first conversion module is configured to convert the analog feedback signals into digital feedback signals. The correction parameter trainer is configured to determine a correction parameter according to the digital feedback signals and a forward signal inputted. The signal distortion correction network module is configured to correct the forward signal based on the correction parameter and output a pre-corrected signal.
