ABSTRACT:
A method, apparatus and article of manufacture for decoding concatenated codes includes (in terms of the method): receiving data representing concatenated codes; first inner decoding the received data resulting in first inner message data and parity data; first outer decoding the first inner message data, resulting in reliability information and first outer message data; second inner decoding the first outer message data, resulting in second inner message data; and second outer decoding the second inner message data. The second inner decoding is a function of: the reliability information from the first outer decoding; the first outer message data; and the parity data from the first inner decoding.
