Optimization of 16-QAM Constellation in the Presence of Nonlinear Phase Noise
Paper i proceeding, 2009
Electronic post compensation of nonlinear phase noise (NLPN) in fiber optical communication is analyzed in this paper. An optimized 16-QAM constellation is proposed to further improve the performance of NLPN compensation in electronic domain. With the proposed 16-QAM constellation the optimum launched power is increased by 2 dB while the minimum symbol error rate (SER) is reduced to 10−8. In terms of transmission distance the performance of system is improved by 540 km at the minimum SER of 10−6
