Abstract:
Disclosed in the present application is an encoding method for a multiple-input-multiple-output (MIMO) system. The MIMO system is an N×M MIMO system, and the method comprises: performing channel estimation on received signals, wherein the signals comprise k target signals and k × (k-1) interference signals, and k is min(N, M); acquiring, according to the channel estimation of the signals, estimated phases of the interference signals; acquiring, according to the estimated phases of the interference signals, a coupled power ratio of the interference signals; acquiring, according to the coupled power ratio of the interference signals, a coupled power ratio of the target signals; and feeding the coupled power ratio of the target signals and the coupled power ratio of the interference signals back to a coupling encoder. The present invention enables an MIMO system to employ a fixed antenna spacing to adapt to different transmission distances, thus solving the problem in which a transmission volume is influenced by the transmission distance.
