Abstract :
Extreme densities for information combining are found for two important channel models: the binary-input symmetric parallel broadcast channel and the parity-constrained-input symmetric parallel channels. Following, upper and lower mutual information thresholds are stated for per-bit maximum a posteriori probability (MAP) decoding and low-density parity-check (LDPC) code ensembles.
