Abstract
A multi-stage decoder decodes a block of symbols, received via a noisy channel, to a codeword. The decoder includes multiple sub-decoders connected sequentially, and wherein a next sub-decoder has a slower processing time and better word error rate than a previous sub-decoder, and wherein the next sub-decoder is only executed if the previous decoder fails to decode the block sequence of symbols, and a last sub-decoder is executed until a termination condition is reached.
