This paper researches OFDM system with LDPC.It proposes that,by use of belief-propagation decoder and a simplified high rank QAM algorithm,LDPC code-OFDM systems decreases the implementation complexity while maintaining efficient and reliable transmission.Simulation resultes show that this OFDM system with LDPC has worked well both in AWGN and multi-path fading channels.
