Embodiments of the present invention provide an MIMO detection method, apparatus and system for transmitting a signal. The method comprises: generating a corresponding first channel matrix by removing a group of column vectors from an original channel matrix; obtaining an equivalent channel matrix by multiplying a conjugate transposition matrix of the first matrix by the first channel matrix, and obtaining an equivalent receiving signal vector by multiplying the conjugate transposition matrix of the first matrix by an original receiving signal vector; obtaining a Euclidean distance set by calculating the equivalent receiving signal vector and a Euclidean distance of a first vector; and forming a second transmitting signal vector set by using the Euclidean distance set, and detecting a transmitting signal vector according to the original receiving signal vector, the original channel matrix, the second transmitting signal vector and the second transmitting signal vector set. Therefore, the calculation complexity is reduced. |
