Abstract

The present invention relates to communication technology. The present invention solves the disadvantage that the detection complexity is too high to be implemented when there are many transmission signal paths in the existing combined input signal MIMO wireless communication system, and provides a combined input signal MIMO wireless communication receiving end and a signal detection method thereof , the technical solution can be summarized as follows: combined input signal MIMO wireless communication receiving end, its reference signal input end is connected to the system state information processing module, multiple receiving antennas are connected to the linear detection module, and the linear detection module is connected to each maximum likelihood detection module respectively. The modules are connected, each maximum likelihood detection module is connected to each corresponding system output terminal, and the system state information processing module is respectively connected to each maximum likelihood detection module, linear detection module and each system output terminal. The beneficial effect of the present invention is that the complexity is relatively low, and it is suitable for combining input signal MIMO wireless communication systems.

Description

technical field [0001] The present invention relates to communication technology, in particular to the technology of wireless communication system. Background technique [0002] The existing NOMA-MIMO (Non-Orthogonal Multiple Access-Multiple Input Multiple Output) system uses a power multiplexing method to improve system capacity and spectrum efficiency, which is characterized by assigning different signal power to different users through power multiplexing technology at the transmitting end , the signals of different users are distinguished by Serial Interference Cancellation (SIC) at the receiving end. [0003] SIC adopts the strategy of eliminating interference step by step, and judges users one by one in the received signal, first subtracts the multiple access interference generated by one user from the received signal, and then makes judgments and multiple access interference on the remaining user signals one by one Eliminate, and operate in a loop until all multiple a...
