PROBLEM TO BE SOLVED: To obtain a wireless communication system on the assumption that a plurality of MTs (communication devices) simultaneously access an AP (communication device) in an MIMO system. SOLUTION: An AP 11 which realizes communications with MTs (1, 2) using an SDM channel corresponding to a plurality of antennas packaged in the present device comprises a transmission signal generating means (synchronizing signal generating section 76 or the like) for applying predetermined transmission processing (including GI addition processing) to a plurality of signals to be transmitted to the MTs, further generating an individual known signal for synchronization for each SDM channel and then generating a transmission signal by inserting the known signal for synchronization into a predetermined position of the GI added signal, and an antenna selecting section 77 for assigning the transmission signal individually generated for each SDM channel to each of the antennas, and a transmission timing of each of the MTs is controlled so that a reception signal arrival time difference on all the SDM channels is settled within GI.
