    Abstract: A data transmission device includes a de-interleaver configured to receive, from a host device at a first data rate, a data stream including encoded data, de-interleave the data stream into a plurality of forward error correction (FEC) data streams, and output the plurality of FEC data streams at a second data rate less than the first data rate. Each of a plurality of interleavers is configured to interleave a respective one of the plurality of FEC data streams into an intermediate data stream including first data blocks and second data blocks. An encoder module configured to generate, for each of the intermediate data streams, FEC blocks including a first parity section and a first data section, the first parity section including a first parity bit corresponding to the first data blocks and a second parity bit corresponding to the second data blocks, and the first data section including the first data blocks and the second data blocks, and output the FEC blocks at the second data rate.

    Abstract: A reception device includes: a receiver that receives a multiplexed signal; a first demapper that demaps the multiplexed signal, with a second modulated symbol stream being included in the multiplexed signal as an undetermined signal component, to generate a first bit likelihood stream; a second demapper that demaps the multiplexed signal, with a first modulated symbol stream being included in the multiplexed signal as an undetermined signal component, to generate a second bit likelihood stream; a first decoder that performs error control decoding on the first bit likelihood stream; and a second decoder that performs error control decoding on the second bit likelihood stream. The multiplexed signal is a signal on which the first modulated symbol stream and the second modulated symbol stream are superposed, the second modulated symbol stream being subjected to conversion in accordance with the first modulated symbol stream in only a first direction.

    Abstract: Methods, systems, and apparatuses are provided for performing joint source channel decoding in a manner that exploits parameter domain correlation. Redundancy in speech coding and packet field parameters is exploited to generate conditional probabilities that a decoder utilizes to perform joint source channel decoding. The conditional probabilities are based upon correlations of parameters of a current frame with parameters of the same or other frames or historical parameter data. Parameter domain correlation provides significant channel decoding improvement over prior bit domain solutions. Also provided are methods, systems, and apparatuses for utilizing received statistics of monitored data bits from which conditional probabilities are generated to perform channel decoding. The techniques described may be implemented at the decoder side and thus do not interfere with transmission standards.

    Abstract: Embodiments of the present invention provide a decoding method and apparatus. The method includes: acquiring a demodulation signal; acquiring a first decoding signal, where the first decoding signal is a signal fed back after the ith M-ary differential decoding processing is performed on the demodulation signal, and i is an integer greater than or equal to 0; and performing M-ary differential decoding processing on the demodulation signal according to the first decoding signal, to obtain a second decoding signal. The first decoding signal that is fed back is added and input to a decoder.
