Increasing demand of high data rate applications at low cost, wireless communication is the key area of research, the solution to this problem is orthogonal frequency division multiplexing (OFDM). Multiple access and forward error correction (FEC) technique like OFDM with low density parity check (LDPC) and low density signature is the best choice over classical OFDM. This paper proposes joint sparse graph OFDM using low density parity check coding by combining joint sparse graph OFDM transmission techniques. The different low complexity transceiver structure joint multiuser detection and FEC decoding and shown numerical. In this paper propose JSG OFDM using LDPC coding that achieves significantly better BER (bit error rate) performance than JSG OFDM for several different system configurations.
