ABSTRACT:
A method decodes a digital information signal which has been coded using a first error correction code and then coded again using a second error correction code. This method comprises the steps of decoding (104) and correcting errors (106) in the coded digital information signal using a decoder corresponding to the second error correction code to produce a first corrected signal. In addition, the method includes the steps of decoding the first corrected signal to obtained position of erasures (108). Next, the erasure location polynomial (112) and modified syndrome components (114) are computed followed by generating an error evaluator polynomial (118) when the modified syndrome components are all zeroes (116). The method also includes the step of calculating error values (120) and correcting errors (122)in the first corrected signal to produce the digital information signal.
