Abstract :
This paper investigates a low-density parity-check (LDPC) coded orthogonal frequency-division multiplexing (OFDM) wireless communication system based on IEEE 802.11a standard. And an initialization algorithm is proposed for the decoding of LDPC coded modulation in OFDM system. The LDPC decoding procedure is simplified without the estimation of channel noise power. Simulation results show that this algorithm is effective and the decoding performance is satisfied when maximum iteration number is 10.
