Abstract
Official abstract text for this publication.
In a cyclic code decoding method, a decoder analyzes a received codeword to identify unreliable symbols in the codeword, and sets candidate syndrome patterns accordingly. Then, a syndrome calculator calculates evaluated syndrome values associated with one of the candidate syndrome patterns, and an error location polynomial (ELP) generator generates an ELP according to the syndrome values. An error correction device corrects the errors in the codeword according to the ELP when a degree of the ELP is not more than a threshold value, and the syndrome calculator adjusts the syndrome values and the ELP generator generates another ELP according to the adjusted syndrome values when otherwise.
First claim
Opening claim text (preview).
What is claimed is: 1. A cyclic code decoding method having an error correcting capability for correcting a maximum number of correctable errors in a received codeword that has a plurality of symbols, said cyclic code decoding method to be implemented using a cyclic code decoder that includes a syndrome calculator, an error location polynomial generator, and an error correction device, and comprising the following steps of: a) configuring the cyclic code decoder to analyze the rec…
