Optimum Signal Constellation Design for High-Speed Optical Transmission

Ivan B. Djordjević, Tao Liu, Lei Xu, Ting Wang

Abstract

We describe an algorithm to determine the optimum signal constellation in MMSE- sense for channel capacity achieving source distribution, and demonstrate that the signal constellations obtained by this algorithm outperform conventional QAM constellations (~1 dB for 16-ary constellation at BER of 10-8).
