Abstract:
A receiver comprising:a demodulator obtaining a reception sequence by demodulating a reception wave which is modulated by an M-ary modulation scheme and is received from a transmitting end via a radio channel;a decoder generating a decoded symbol sequence by carrying out a maximum likelihood decoding with respect to the reception sequence obtained by said demodulator; anda demapping part reading the decoded symbol sequence generated by said decoder, and restoring a transmission unit of the reception wave by carrying out a demapping adapted to a format of a set partitioning carried out by a mapping at the transmitting end which transmits the reception wave based on transmission information using a plurality of encoding schemes, one of said encoding schemes using a repetition code,said decoder carrying out the decoding using a trellis diagram which is given as a combination of sub-trellis diagrams independently corresponding to logic values of the repetition code.
