Abstract

The signal constellations used in optical communication systems with intensity modulation are different than those in radio frequency communication systems. In this paper, we propose a four-symbol constellation called C4, in which three symbols have the equal radius. We investigate its symbol probability rate (SER), and compare with another popularly used four-symbol constellation. The result shows that the average SER profiles of two constellations are quite close, while C4 has a much smaller peak-to-mean-electrical-energy-ratio (PTMER).
