摘要： A system and method are provided for implementing a soft Reed-Solomon (RS) decoding scheme, technique or algorithm to improve physical layer performance in cable modems and cable gateways. At 1024-QAM, a receiver is provided in which a signal to noise ratio is reduced by at least about 1 dB relaxing design considerations and specifications for other components in the system including for the tuner. A soft-RS-symbol generation scheme is provided to enable soft-input RC decoding in a forward error correction (FEC) module connected to a QAM demodulator. The RS decoding scheme is implemented without significantly complicating hardware or processing overhead. A typical receiver hardware requirement in an FEC module to implement the disclosed scheme may be comparatively modest, e.g., on an order of approximately 50K gates.

摘要： Apparatus and methods are provided for differential decoding in a communication system, such as a cable system, that enable use of Chase algorithm for Reed Solomon (RS) codes (i.e., non-binary codes). A differential decoder (170) has a memory for storing a current decoder input and a previous decoder input. Each decoder input comprises a first candidate (Input Constellation Candidate #1), a second candidate (Input Constellation Candidate #2) and a reliability score (Score). A first branch comprises a first differential decoder (192) and corresponds to the first candidate. A second branch comprises a second differential decoder (196) and corresponds to the second candidate. A processing circuit (190) is operative to determine whether a previous decoder input is a boundary point, and if not, a current first candidate is applied to the first differential decoder (192) and a current second candidate is applied to the second differential decoder (196). If a previous decoder input is a boundary point and a current input score is greater than a previous input score, a first current candidate is applied to the first differential decoder and the second differential decoder and a second differential decoder memory is set to the contents of a first differential decoder memory. If a previous decoder input is a boundary point and a current input score is not greater then a previous input score, current first and second candidates are applied to the first and second differential decoders, respectively.
