Abstract: A method for detecting a spatial multiplexing symbol is provided to decrease a calculation amount of a system by defining an arrangement criterion of a channel matrix by decomposing the channel matrix and arranging the channel matrix using the arrangement criterion. A measured channel matrix is expanded according to a variance of a noise to define an expanded channel matrix. An order arrangement criterion is defined by using the expanded channel matrix. The expanded channel matrix is arranged by using the order arrangement criterion, and sequence arrangement information is obtained. Actual power is allocated on a transmitter side by using the expanded channel matrix. The expanded channel matrix is arranged by using the order arrangement information. The expanded matrix is QR-decomposed, such that candidate transmission symbol is detected.
