Parallel concatenated Gallager codes for CDMA applications
We present a class of concatenated codes called parallel concatenated Gallager codes (PCGC) using low-density parity-check (LDPC) component codes. We report simulation results for PCGC that outperform those for comparable LDPC codes both in additive white Gaussian noise (AWGN) and flat Rayleigh fading channels. The good performance of PCGC increases the capacity of CDMA systems while the reduced encoding and decoding complexity of such codes keep the signal processing delays within a reasonable limit.
