摘要： A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts (11—1-11—4) that encode transport data; a mapping part (3304) that performs such a mapping that encoded data sequentially formed by the encoding parts (11—1-11—4) are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver (3301) that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

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 64QAM-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).
