TRANSMISSION SIGNAL GENERATING APPARATUS AND METHOD, AND RECEPTION DATA GENERATING APPARATUS AND METHOD

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.

1. A transmission signal generating apparatus comprising:
an encoder that performs error correction encoding processing on transmit data comprising a plurality of bits to form a plurality of error correction encoding data each comprising a plurality of bits; an interleaver that interleaves bits of the plurality of error correction encoding data; and a modulator that modulates the interleaved bits of the plurality of error correction encoding data using a QPSK modulation scheme or a 16QAM modulation scheme to generate a plurality of modulation symbols, wherein: the modulator generates the plurality of modulation symbols, using a first error correction encoding data for the QPSK modulation scheme, and, using the first error correction encoding data and a second error correction encoding data for the 16QAM modulation scheme, at a first time slot; and the interleaver interleaves the bits for every two bits in the QPSK modulation scheme and interleaves the bits for every four bits in the 16QAM modulation scheme.
