<P>PROBLEM TO BE SOLVED: To provide transmission and reception systems of MC-CDMA whose hardware scale of STTD does not become large, and can be realized on a small scale hardware even when the subcarrier number of MC-CDMA increases, and a wireless radio communication system equipped with the reception and transmission systems. <P>SOLUTION: The reception system is equipped with two or more receiving antennas, two or more MC-CDMA reception means with perform a serial/parallel conversion, a fast Fourier transformation, despreading, equalization and synthesis for each of received signal of the two or more receiving antennas, a space-time decoding means which performs decoding in the time direction and the space direction for an output signal of the two or more MC-CDMA reception means,a parallel/serial conversion means which converts an output signal of the space-time decoding means to a serial signal, a demapping means which decodes an output signal of the space-time conversion means, and a decoding/deinterleaving means which perform deinterleaving of an output signal of the demapping means and an error correction decoding, and restores the transmitted data. <P>COPYRIGHT: (C)2004,JPO |
