  • Reed-solomon decoder
    Patent number: 9166623
    Abstract: A system and method of decoding a Reed-Solomon code using a Reed-Solomon decoder comprising an erasure location selector, multiple syndrome formers and multiple Berlekamp-Massey decoders that share a single error correction unit, and means for selecting a Berlekamp-Massey decoder output as the input to the error correction unit. The method improves the bit error rate performance of the Reed-Solomon decoder compared to known hard-decision and soft-decision Reed-Solomon decoders. The Reed-Solomon decoder also provides hardware area and power savings over more complex Reed-Solomon decoders.

  • Cyclically interleaved dual BCH, with simultaneous decode and per-codeword maximum likelihood reconciliation
    Patent number: 8479084
    Abstract: A method and system are provided for forward error correction. Embodiments of the present disclosure provide a strong FEC algorithm that performs similarly to RS(255,239) when a simple decoder is used, and scales up linearly to a full-scale decoder that outperforms all 7% algorithms currently in G.975.1. The Forward Error Correction code is suitable for use in optical transport networks (OTN) and other applications requiring high decode performance and high code rate. Embodiments of the present disclosure provide an FEC code that is a cyclically interleaved dual BCH, with simultaneous decode and per-codeword maximum likelihood reconciliation.
