Summary:PROBLEM TO BE SOLVED: To solve the problem wherein research for the MIMO (Multiple-Input Multiple-Output) system which uses a plurality of antennas for transmission and a plurality of antennas for receiving has increased recently, in response to an increasing demand for high-speed and large-capacity communication in radio communication, however, since the MIMO system is capable of multiplexed signal transmission at the same frequency, and at the same time, it has become clear that the channel capacity increases the number-of-antennas min (M, N) times than in the SISO (Single-Input Single-Output) system, where M is the number of transmitting antennas and N is the number of receiving antennas, a frequency selective channel, having a delay in channels between antennas suffers from degradation of characteristics due to the influence of delay waves and interference waves. SOLUTION: As a data transmission method in a frequency selective MIMO channel system, eigenmode transmission is realized, by inserting zero zones that are called "guard intervals" into a signal, in advance, on the transmitter side in the MIMO eigenmode system.
