摘要： A transmitter apparatus wherein a relatively simple structure is used to suppress burst errors without changing the block sizes of encoded blocks even when the number of modulation multi-values is increased. An encoding part subjects transport data to a block encoding process to form block encoded data. A modulating part modulates the block encoded data to form data symbols; and an arranging (interleaving) part arranges (interleaves) the block encoded data in such a manner that the intra-block encoded data of the encoded blocks, which include their respective single different data symbol, get together, and then supplies the arranged (interleaved) block encoded data to the modulating part. In this way, there can be provided a transmitter apparatus wherein a relatively simple structure is used to suppress burst errors without changing the block sizes of encoded blocks even when the number of modulation multi-values is increased.

摘要： It is possible to demodulate a plurality of modulated signals transmitted from a plurality of antennas by using a comparatively small-size circuit with a preferable error ratio characteristic. Partial bit judgment units (509, 512) demodulates partial bits of the 64 QAM-modulated signal by modifying which of the bits in the 6-bit strings constituting a symbol is to be demodulated depending on in which region of the IQ plane the reception signal point exists. This improves the partial bit error characteristic judged by the partial bit judgment units (509, 512), which in turn improves reliability of the reduced candidate signal point for use by a likelihood detection unit (518). As a result, it is possible to improve the error ratio characteristic of the final reception digital signals (322, 323).

摘要： The error correcting decoding device of the present invention performs Low-Density Parity-Check (LDPC) decoding which accommodates a plurality of code rates while sharing circuits to suppress increase in circuit scale. If the set code rate is a second code rate which is a higher code rate than a first code rate, a column processing and row processing calculating unit (120A) uses a distributed submatrix in which a number of columns are selected and combined, wherein the number of columns is equal in number to the number of columns with which a first submatrix is constructed from a distributed check matrix corresponding to a second check matrix which accommodates the second code rate. At this time, the column processing and row processing calculating unit (120A) uses a distributed submatrix such that the row degree is less than or equal to the row degree of the first submatrix.
