Refinements of the Threshold Error Correcting Algorithm

Refinements of the convolutional codes which were presented at the 67th AES Convention are examined. These refinements are feedback and multiple decoding. Using these improvements, it is possible to correct noisy signals having bit error rates of the order of 1E-2 to one uncorrected error per hour. By interleaving or by increasing tap spacing, error bursts up to several thousand bits may be corrected. The addition of a parity bit which may be used for error concealment is also discussed. Error concealment techniques evaluated by listening tests will be reported. Implementation of both refinement schemes in hardware is of the same order of simplicity as the original mode.
