ABSTRACT:
A concatenated coding scheme having at least two levels of coding. According to the exemplary embodiments, a first decoding scheme is used to decode a demodulated sequence provided that the mathematical combination of the number of computations and the amount of memory required to decode the sequence does not exceed a threshold value. If the threshold value is exceeded, due to, for example, excessive noise in the channel, a secoding decoding scheme is used to decode the sequence.
