Abstract:
1. A receiving apparatus comprising: a receiver configured to receive a modulation symbol sequence; and a decoder configured to decode the received modulation symbol sequence, wherein the decoder comprises: a first decoder configured to decode a first bit group included in the each received modulation symbol by a first decoding scheme, the first bit group being encoded by a first encoding process; and a second decoder configured to decode a second bit group included in the each received modulation symbol by a second decoding scheme, the second bit group being a bit group other than the first bit group, and encoded by a second encoding process different from the first encoding process, and wherein the first bit group comprises a plurality of bits indicating one of four regions on an IQ plane, the four regions on the IQ plane being regions into which a mapping pattern of the received modulation symbol sequence is divided, and the second bit group comprises a plurality of bits indicating a position of the received modulation symbol sequence in the one of the four regions on the I-Q plane, and the first encoding process has higher error correction capability than the second encoding process.
