RADIO COMMUNICATION SYSTEM AND TRANSMITTER

摘要

A radio communication system according to the present invention comprises a transmitter (2B) having a plurality of transmission antennas, and a receiver (5) having a mechanism to perform a diversity reception. A plurality of multi-modulators (3A, 3B) of the transmitter (2B) 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. <IMAGE>
