Abstract

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.

Sphere decoder with box optimisation for faster‐than‐Nyquist non‐orthogonal frequency division multiplexing

In 1975, J. E. Mazo showed the potential faster‐than‐Nyquist (FTN) gain of the single‐carrier binary signal. If the inter‐symbol interference is eliminated by an optimal detector, FTN single‐carrier binary signal can transmit 24.7% more bits than the ...

In this paper, a carrier recovery algorithm for high-order cross-QAM has been proposed, in which less than twelve symbol points in the constellation have been used. The proposed algorithm can be applied to square QAM signals as well. The simulation ...
