Abstract :
Low-density parity check coded bit-interleaved coded modulation (BICM) schemes are analyzed in this paper. A simplified decoding method without iteration between demodulator and decoder is provided. And the performance over additive white Gaussian noise (AWGN) and Rayleigh fading channels are analyzed. Through the simulation results we can conclude that the schemes with low complexity decoding method have good performance both over AWGN and Rayleigh fading channels.
