摘要：
The nonlinear transmission and phase noise tolerance performance of three different 8-ary constellations (8PSK, star-shaped 8QAM and circular 8QAM) in coherent optical communication systems are investigated with the improved Viterbi-Viterbi algorithms for carrier phase estimation and radius-directed linear Kalman filter for polarization de-multiplexing.
