In detail  the rapid synchronization method to reduce the handshake bandwidth requirement is demonstrated. The hardware of the system includes the laser driver system  the signal amplifying and shaping system  the data interface system. The hardware specified physical layer protocol is used to interface the outer data  serialize and deserialize the data stream  check transmission errors and schedule the data transmission. The overall system is a FIFO-like system and the user can use it as if he's operating a FIFO. The system is designed mainly for terrestrial FSO link whose signal channel is the atmosphere. Due to the complex composition and activity of the atmosphere  this signal channel brings in great influence on the transmitting laser in it  for example  the absorption and scattering of the atmosphere molecules and aerosols  the scintillation of received laser power caused by the turbulence of the atmosphere  all of which results in a much higher Bit Error Rate (BER) of the communication system than wired communication systems leading to frequent resynchronization. In our system  the sampling clock is generated locally using multi-phase sampling technique rather than PLLbased clock recovery  which helps to rapid synchronization. 2012 IEEE.   The transmission link of CAPS navigation and communication system 期刊论文  OAI收割 SCIENCE IN CHINA SERIES G-PHYSICS MECHANICS & ASTRONOMY, 2009, 卷号: 52, 期号: 3, 页码: 402-411 作者:  Cui JunXia;  Shi HuLi;  Chen JiBin;  Pei Jun 收藏  |  浏览/下载：22/0  |  提交时间：2017/04/11 satellite navigation  satellite communication  transmission link  link margin  demodulation threshold  CAPS
