Disclosed in the present disclosure are a signal detection method and device. The method comprises: according to a signal received by each antenna, performing a channel estimation, and acquiring channel estimation matrixes of all transmitting users reused on same time-frequency resource on each antenna, and according to a PDMA coding matrix, determining an equivalent PDMA channel estimation matrix of each antenna, and according to the equivalent PDMA channel estimation matrix of each antenna, acquiring the equivalent and multi-antenna PDMA channel estimation matrix of all antennas; according to the equivalent and multi-antenna PDMA channel estimation matrix, equivalent and multi-antenna vector of the received signal, and constellation point sets of all transmitting users reused on the same time-frequency resource, performing a combined detection, and acquiring LLRs of all transmitting users; decoding LLRs of all transmitting users, and acquiring multi-user information of a sender. |
