<p>This invention provides a MIMO communication system and MIMO communication method. A MIMO receiver (200) estimates state of each communication channel from the received signals received by #1 to #L antennas (102), generates feedback information according to the information of channel state, sends the feedback information to a transmitter (100) through a feedback path (400), processes the feedback information in order to compensate feedback-delay of the feedback path, generate (212) K*L proper reception weights by using the information of channel state and processed feedback information, multiplies the received #1 to #L sub-streams of respective #1 to #K signal streams by the proper #1 to #L reception weights, respectively, composes the #1 to #L weighted sub-streams to obtain respective composed #1 to #K signal streams and demodulate (210) the composed #1 to #K signal streams, respectively, and combines (208) the demodulated K signal streams to reproduce an original transmission signal.</p> |
