Your library or personal account may give you access

Abstract

We present a novel LDPC coded IM/DD optical OFDM system. A method of evaluating the LLR is proposed for soft demodulation. The simulation results demonstrate that the system with code rate R=1/3 has NCG of lager than 10dB at the BER= 1E-3 over 40-km transmission.
