Based on the theory of chaotic synchronization, a chaotic transmitter and receiver circuit with low noise was proposed, and the principles of synchronization and secure communication were expounded.
基于混沌同步理论，设计出低噪声的混沌发射机和接收机电路，阐述了实现同步和保密通信的原理。

The transmitter beam is Gaussian for real satellite-ground laser communication system. The pointing jitter and atmospheric scintillation are the main noise sources for satellite-ground laser link.
实际星地光通信系统的发射光束为高斯型的情况下，跟瞄误差和大气闪烁是星地激光链路中的主要信道噪声源。
