摘要
设计了一种回复反射式大气激光通信系统,可免去传统大气激光通信链路中一个终端的激光发射器和跟瞄系统。在多路并行传输情况下,为了解决各路信号之间的干扰问题,提出了一种基于盲源分离算法的多路信号分离方案。仿真实验表明,算法分离效果理想,在信道条件发生变化时,仍能准确分离出源信号的波形信息。
The paper designs a reply to reflex atmospheric laser communication system,with which a laser transmitter and a tracking system can be avoided in traditional atmospheric laser communication link. Under the condition of the multi-channel parallel transmission, in order to solve the interference problem between multiple signals, the paper proposes a multi-channel signal separation based on blind source separation algo- rithm. Simulation results show that the effect is ideal, and it can also separates the accurate waveforms of source signals when channel condition changes.
