<P>PROBLEM TO BE SOLVED: To provide a device for increasing transmission capacity by simultaneously transmitting different data sequences from a plurality of antennas using the same frequency about an MC-CDMA system transmitter and receiver. <P>SOLUTION: This transmitter 1 has an encoding interleaving means 12, a mapping means 13, an SDM (space division multiplexing) pilot signal inserting means 14, an MC-CDMA transmitting means 15 and a plurality of transmitting antennas 16 for each of a plurality of pieces of different transmission data. On the other hand, the receiver 2 has a plurality of receiving antennas 21 which are as many as the transmitting antennas of the transmitter, and a guard interval means 221 and an MC-CDMA receiving means 22 for reception signals received by the respective receiving antennas. <P>COPYRIGHT: (C)2004,JPO |
