The present invention provides a signal detection method and apparatus in a spatial multiplexing system. According to the present invention, the signal detection apparatus of a single receiver is formed with a plurality of antennas in a system in which at least one transmitter transmits data streams by a spatial multiplexing method, the signal detection apparatus comprises: a partial linear coefficient generator which generates a linear weight matrix by using the preset algorithm in a channel matrix that is formed between the at least one transmitter and a single receiver; a partial symbol eliminator which generates a first symbol vector by eliminating all transferable symbols of each transmission antenna in all of the data streams received; and a partial symbol detector which generates a transmission symbol candidate vector by using the first symbol vector and the generated linear weight matrix. Thus, according to the present invention, there is no big performance difference of errors between the data streams. |
