摘要 提出了一种新型的用于大气激光通信的6偏振键控调制方式,理论分析和仿真结果表明,光信号的偏振态和偏振度在不同大气信道模型中经过长距离传输后保持不变,因此在大气激光通信中可以采用偏振键控的调制方式。多级调制方式可以提高系统频谱效率,利用光信号的6种偏振态来传输信息将大大提高系统的带宽效率,6偏振键控调制是适合大气激光通信系统传输速率和带宽效率的一种具有吸引力的调制方式。 A modulation scheme of 6-PolSK for atmospheric laser communication is proposed. Theoretical analysis result demonstrates that the states of polarization (SOPs) and degree of polarization (DOP) of light wave can be well maintained after long distance propagation in the atmospheric channel with different turbulence models. Simulation results show that the transmission performance and the bandwidth efficiency are improved considerably. 6-PolSK modulation is an attractive approach to meet the criteria about data rate and bandwidth efficiency of the atmospheric laser communication system,
