为了解决激光通信中符号同步传输效率低问题,采用了超帧同步取代符号同步方法。在分析多脉冲位置调制码型和帧长的特点基础上,详细分析了不同的组合巴克码做多脉冲位置调制超帧同步码的方法,计算了不同长度帧的同步码长度。仿真结果表明,这种方法能实现二进制数据的正确解调。该研究结果对提高激光通信同步性能具有一定的理论参考价值。

In order to solve the low efficiency problem of symbol synchronization in laser communication,a super-frame synchronization was proposed instead of symbol synchronization.On the basis of analyzing multi-pulse position moudulation (MPPM) code pattern and length,the different methods of combination Barker sequence applied in the super-frame synchronization of MPPM were analyzed,and the length of synchronization code of the different frame was calculated.The simulation results show that this method can decode the input binary bits accurately.The obtained results have theoretic reference value for the improving the performance of laser communication.
