Abstract :
Coded modulation is a bandwidth efficient scheme that combines the functions of coding and modulation. We proposed a new scheme of low-density parity-check coded modulation. Its performance is also analyzed over AWGN and Rayleigh fading channels. Both theoretical analysis and simulation results show that this new scheme can obtain better performance of bit error rate without increasing bandwidth for both AWGN and Rayleigh fading channels.
