In an error correction method, a codeword is transmitted through a noisy communication channel and detected by a receiving device. An error detection code is then applied to the detected codeword to generate a syndrome. Where the syndrome is not all zero, the codeword is determined to contain some error. Accordingly, the method computes a set of potential error start positions for a plurality of error events based on a syndrome value corresponding to the syndrome. Next, a confidence value is computed for each of the plurality of error events at each of the potential error start positions in the refined set, and finally, a most likely error event in the detected codeword is corrected based on an error event and corresponding potential error start position having the highest confidence value.
A method of processing a detected codeword transmitted through a communication channel based on error events commonly produced in relation to the communication channel, the method comprising:
A non-transitory computer-readable data storage medium adapted to store recorded data, wherein the data can be read by encoding the data as a codeword and transmitting the codeword across a readback channel such that a receiving device can perform error correction on the codeword using a method comprising:
