Abstract :
A new decoding method, called extrinsic tree decoding, is presented for decoding low-density parity-check codes on modified finite computation trees. The proposed method maintains similar performance to that of existing iterative decoders, while providing a decoding method for which realistic upper bounds can be computed for practical codes.
