Abstract
Digital data is processed by quantizing the data to produce samples, each with a most significant bits and least significant bits with the least significant bits representing reliabilities, generating a parities from the most significant bits of the samples, generating weight functions corresponding to the parities on the basis of the number of times a reliability measure occurs, and producing a corrected stream of data with the weight functions and the corresponding parities.
