In this letter, we propose the Low-Density Parity-Check (LDPC) coded Orthogonal Frequency Division Multiplexing (OFDM) systems to improve the error rate performance of OFDM. We also evaluate the iterative decoding performance on both an AWGN and a frequency-selective fading channels. We show that when the energy per information bit to the noise power spectral density ratio E_b/N_o is not small, the LDPC coded OFDM (LDPC-COFDM) systems have the good error rate performance with a small number of iterations We also show that when the E_b/N_o is small, the BER of the LDPC-COFDM systems is worse than that of the Turbo coded OFDM (TCOFDM) systems, while when the E_b/N_o is not small, the BER of the LDPC-COFDM systems is better with a small number of iterations.
