Abstract

To meet the demands of different high bandwidth service, OFDM-PON has been considered as one of the candidates for NG-PON2. In this paper, downstream transmission performance based on LDPC-OFDM coding PON system is studied. The simulation results show that employing the LDPC-OFDM coding in PON system can achieve 10 Gb/s downstream transmission. The transmission performance of the LDPC-OFDM system is improved 4.2 dB than uncoded system at the BER of 10-4. When the SNR is greater than 2. 6 dB, the Gallager method has better BER performance than the Mackay and BIBD construction schemes, and when the SNR is greater than 4. 6 dB, LLR-BP and the improved decoding algorithm enables to improve system performance.
