Reliable channel regions for good codes transmitted over parallel channels

This paper describes a given ensemble of good binary codes and a codeword-symbol with channel assignment rule and error probability performance. The reliable channel regions based on the parallel-channel Gallager bound achieves all functions of the code weight enumerators, parallel-channel transition probabilities, and the channel assignment rates. The channel model consists of parallel binary-input symmetric-output (BISO) discrete memoryless channels. The uniform codeword partition and decoded iteratively of a reliable channel regions for good codes transmitted over parallel channels is studied.
