REED-SOLOMON ERASURE DECODING WITH ERROR DETECTION FOR RETRANSMISSION |
摘要 |
By utilizing Reed-Solomon erasure decoding algorithms and techniques, the system is able to perform error detection for the case where the number of bytes received in error exceeds a correcting capability of a decoder. The error detection can be used, for example, to determine whether a codeword is decodable, and whether the retransmission of data is necessary. The retransmission can be accomplished by assembling a message that is sent to another modem requesting retransmission of one or more portions of data, such as one or more codewords. |

1. A method to determine a decodability of a codeword in a communications environment comprising:
assigning or obtaining reliability metrics for a plurality of bytes in the codeword; determining a score for a plurality of codeword decoding solutions based on the reliability metrics; comparing the score to a correctability threshold; and determining whether the codeword is decodable. |
