The invention belongs to the technical field of communication, and relates to a spatial modulation signal detection method. Angular distances are sorted, so that the number of constellation points of each transmitting antenna needing to perform ML detection is reduced; furthermore, when the angular distances are obtained, only subtraction needs to be performed; therefore, when the constellation points needing to perform ML detection are reduced, extra multiplication cannot be introduced; furthermore, comparing and sorting operations in a signal demodulation process can be avoided through a corresponding table of angles and the constellation points to be detected, so that the detection complexity is further reduced; for non-M-PSK modulation, the real multiplication time required by the invention is shown in the specification; for M-PSK modulation, the real multiplication time required by the invention is (6Nr+4)Nt; when the same detection performance is achieved, the real multiplication time required by the in
