    摘要： The present invention provides a decoding method, a decoding apparatus, and a communications system, which implement multi-level coding in a manner combining soft-decision error correction coding and hard-decision error correction coding, implement multi-level decoding in a manner combining soft-decision error correction decoding and hard-decision error correction decoding, so as to integrate advantages of the two manners: compared with a manner in which soft-decision error correction coding and decoding are performed on multiple levels, a manner in which soft-decision error correction coding and decoding are performed on only one level reduces system complexity and resource overhead; and performing hard-decision error correction coding and decoding on other levels on a basis of performing soft-decision error correction coding and decoding on one level ensures gain performance, thereby meeting a gain requirement of a high-speed optical transmission system.

    摘要： Methods and apparatus for use in communication systems using recursive modulation schemes with a Low Density Generator Matrix code (including an irregular repeat accumulate (IRA) code) are described that have reduced complexity and thus reduced cost compared to prior art systems. A communication system is described in which the transmitter concatenates a low density generator matrix code with an accumulator followed by a recursive modulator in order to eliminate the use of an interleaver, and in which the receiver combines the decoder for the accumulator and the soft demodulator into a single joint decoder in order reduce the number of components and complexity. Another variation is also described in which the transmitter is further simplified by eliminated the accumulator altogether, and in which the receiver is further simplified by replacing the joint decoder with a soft demodulator prior to the LDGM soft decoder.

    摘要： A soft output detector is programmed with a first set of parameters. Soft information is generated according to the first set of parameters, including likelihood information that spans a maximum likelihood range. Error correction decoding is performed on the soft information generated according to the first set of parameters. In the event decoding is unsuccessful, the soft output detector is programmed with a second set of parameters, soft information according is generated to the second set of parameters (including likelihood information that is scaled down from the maximum likelihood range), and error correction decoding is performed on the soft information generated according to the second set of parameters.

    摘要： Systems, devices and techniques for soft-in, soft-out (SISO) decoding can include accessing initial soft information on a series of data units received over a communication channel, using a cyclic graphical model to represent a coding scheme associated with the received data units, obtaining cycle-free graphical models for a plurality of second conditions allowable by the coding scheme, and generating soft-out decision information by using information that includes the obtained cycle-free graphical models and the initial soft information. The number of obtained cycle-free graphical models can be less than a total number of conditions associated with the cyclic graphical model. Soft decision information can include confidence levels for each data unit.
