TRANSMITTING METHOD, TRANSMITTING DEVICE, RECEIVING METHOD AND RECEIVING DEVICE

摘要

A decoding device includes: a BP decoding unit which subjects an input signal to BP decoding; a maximum likelihood decoding unit which subjects the BP-decoded signal to maximum likelihood decoding; and a selecting unit which selects either the input signal, the BP-decoded signal, or the maximum likelihood-decoded signal. Adopting this configuration makes it possible, by causing the decoding unit to operate as appropriate in accordance with the quality of data, for example, to reduce the scale of computations that are performed, and to reduce power consumption.
