Abstract:
A method for determining an overall Chase decoding result for a series of Chase iterations for decoding input data, the method comprising the steps of:performing a portion of an intermediate Chase iteration of the series of Chase iterations to obtain a successful hard-decision decoding result for the input data; determining that the successful hard-decision decoding result comprises the overall Chase decoding result with employment of reliability information for at least one location of the input data and without employment of information that specifies, for the input data, error location within the input data; and wherein the step of performing a portion of the intermediate Chase iteration of the series of Chase iterations to obtain the successful hard-decision decoding result for the input data comprises the step of selecting the intermediate Chase iteration and a Chase iteration of the series of Chase iterations to comprise consecutive Chase iterations, having only one value difference between respective code patterns thereof, of the series of Chase iterations.
