<p>An OFDM signal communication system used in broadband mobile communication, achieves stable operation under severe frequency selective fading environments, giving high quality. The OFDM signal communication system which transmits OFDM signals over the same radio frequency from N transmitting antennas (5-1,...,5-N), has an inverse matrix computer (13) for computing an N x N inverse matrix constituted by propagation coefficients for respective propagation paths between each of N transmitting antennas (5-1,...,5-N) and each of N receiving antennas (8-1,...,8-N), and a subcarrier demodulator (14) which separates the signals of the respective propagation paths, based on the obtained inverse matrix. <IMAGE></p> |
