Abstract
A reception program maps, by PC mapping, the values of message data to symbol x, which describes the combinations of Mcarrier waves of Mcarrier waves with value-1 bits corresponding to the carrier waves to be transmitted, and receives the transmit signal created by performing transformation processing thereon to sample y. A matrix computing portion performs transformation processing on sample y' in a parallel form including an unnecessary signal component to symbol z′. A first decoding portion sequentially performs maximum likelihood value decoding on groups of M bits of symbol z′ and finally decodes all of the symbol z′ to symbol x″. If the symbol x″ includes Mvalue-1 bits, a second decoding portion handles the symbol x″ as the final decoding result and if not, the second decoding portion performs maximum likelihood decoding on the entire symbol z′ to obtain the final decoding result.
