ABSTRACT:
A method for detecting errors in data that comprises encoding the data into a codeword using a generation polynomial, transmitting the codeword over a channel, receiving the transmitted codeword, generating syndromes for the received codeword using the generation polynomial, the syndromes comprising a plurality of syndrome symbols, providing a plurality of syndrome windows, each of the syndrome windows comprising a plurality of sub-windows and corresponding to a set of syndrome symbols, determining a number of non-zero terms of sub-windows of each of the syndrome windows, and selecting at least one syndrome window having a least number of non-zero terms of sub-windows.
