Research of signal tracking technology in FSO communication

Abstract

In the decade of information, with the increment of the data rate and capacity in communication, free space optical communication (FSO) has been paid much attention by many countries since it integrates the advantages of fiber communication and other traditional wireless communication technologies, such as large capacity, low cost, convenient deployment and flexibility. This paper concerns with the research on the signal tracking technology of FSO. Considering that suppressing vibration is a difficulty of FSO, so suppressing methods are discussed in the paper. As a base, the ATP (Acquisition, Tracking, Pointing) technology of FSO communication system is analyzed in this paper. And a new signal tracking system for FSO communication is described. The main structure, integral parts and detailed work process of this signal tracking system are introduced in detail.
