Detection of a signal in a receiver of a MIMO communication system includes a transmitter for signals transmission via K antennas and a receiver for receiving the signals via L reception antennas, such that L is greater than or equal to K and the system has a K&#xd7;L-dimensional channel matrix, by converting the channel matrix into a plurality of matrixes having an upper triangle structure; dividing each of the matrixes into at least two sub-matrixes having a dimension lower than that of the channel matrix; detecting transmission symbols from corresponding antennas through decoding of a) lowest sub-matrix signal received which sub-matrix is constituted of components having only the channel characteristics of two antennas among the two sub-matrixes; and b) an upper sub-matrix signal using the transmission symbols; and outputting all of the detected transmission symbols, if transmission symbols by a highest sub-matrix among at least two sub-matrixes are detected.

Method and apparatus for detecting signal in a MIMO communication system

An apparatus and method for transmitting/receiving data in a multi-user multi-antenna communication system is provided. A data transmitting apparatus and method computes a TX filter of a transmitter in an improved scheme and transmits the computed TX filter to a receiver in a one-way channel sounding scheme. A data receiving apparatus and method receives the TX filter over a channel and uses the product of the received TX filter and a channel matrix as an RX filter.
