In mobile communication, owing to decrease FdTs(Normalized Maximum Doppler Frequency), it is necessary to shorten time domain OFDM(Orthogonal Frequency Division Multiplexing) symbol. For realize keeping bitrate, we made OFDM decoder what have function correcting Doppler shift and receive system what use space diversity by distributing antenna. we realized 10Mbps wireless communication by 5.7GHz/5MHz bandwidth OFDM.
