基于频移键控和最小频移键控的恒包络调制高速光传输

Abstract

A novel 40-Gb/s constant envelope optical frequency shift keying (FSK) transmitter and the transmission characteristics are investigated both by simulation and experiment.Meanwhile, to increase the spectrum efficiency of FSK, we propose a novel optical minimum-shift keying (MSK) scheme and analyze its performance compared with other MSK schemes and other traditional modulation formats.Simulation and experimental results show that the novel FSK scheme could be a potential candidate for the future high speed transmission and label switching systems.And the novel MSK scheme deserves future deep research for its potential excellent performance.
