<P>PROBLEM TO BE SOLVED: To provide a transmission method, which concurrently transmitting a plurality of modulation signals from a plurality of antennas, capable of improving reception quality even under an environment where a direct wave is dominant. <P>SOLUTION: In all data symbols used for data transmission of modulation signals to be transmitted, for precoding matrices used in precoding each of the data symbols and precoding matrices used in precoding data symbols adjacent to the data symbols in the frequency axis direction and time axis direction to be all different from each other, the precoding matrices are switched, the symbols are precoded, and the modulation signals arranged with the data symbols are transmitted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
