A radio communication system according to the present invention comprises a transmitter having a plurality of transmission antennas, and a receiver having a mechanism to perform a diversity reception. A plurality of multi-modulators of the transmitter allocates the same transmission data to a plurality of subcarriers, combines all transmission signals obtained by weighting each of the subcarriers, and outputs combined transmission signals. At least one of weight values for the same data is different between the multi-modulators in the weighting processing for each of the carriers.
