Abstract:
1. A transmitting method that executes encoding processing on transmit data configured by a plurality of bits and forms encoded data configured by a plurality of bits, performs arrangement processing on bits belonging to said encoded data, executes modulation processing on said arranged encoded data and outputs a baseband signal corresponding to a symbol, and transmits a transmit signal based on said baseband signal, wherein: each of said encoded data is assigned per reception terminal; said modulation processing is configured to use a plurality of modulation schemes, and whichever modulation scheme is used, two bits extracted arbitrarily from a plurality of bits configuring said symbol are bits belonging to mutually different encoded data; each bit of said symbol is assigned to a different reception terminal; said encoded data is low density parity-check code (LDPC) encoded data; in said encoding processing said encoded data is configured to be formed using a plurality of different coding rates; in said arrangement processing the bits belonging to said encoded data are arranged so that one symbol is configured by collecting together bits belonging to any of a plurality of said encoded data; and said plurality of encoded data used in said arrangement processing includes at least encoded data formed by a coding rate different from a coding rate of encoded data selected arbitrarily from said plurality of encoded data.
