<P>PROBLEM TO BE SOLVED: To provide a transmitter, etc. for spectrum aggregation which improves frequency diversity gain by transmitting a transmission signal consisting of transmission bit strings per carrier signal which have been interleaved at random across the carrier signals in different frequency bands to impart correlationship to the transmission bit strings. <P>SOLUTION: A transmitter includes interleave means which interleaves each coded bit string output from channel coding means across carrier signals. The interleave means includes: bit string dividing means of dividing across the carrier signals each coded bit string which is output from the channel coding means on the basis of the number of carrier signals, and also executes this dividing operation from a carrier signal having high priority of radio characteristic values on the basis of priority corresponding to radio characteristic values so that many data bits will be included; and bit string multiplexing means which multiplexes, according to symbol mapping, a plurality of coded bit strings per carrier signal which are output from the bit string dividing means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
