Abstract
Free Space Optical (FSO) communication is a communication pattern in which laser is used as the information carrier in atmosphere environment. FSO system has been widely applied in the fields of satellite communication and ground sight distance communication, with a promising application prospect and tremendous market potential. And space-time processing (using multiple antennas) is now recognized as a key to achieving reliable high data rate wireless communications and is being incorporated into the physical layer of many wireless standards. In this letter, error rate performance for space-time block coding (STBC) in FSO communication systems with direct detection operating over strong atmospheric turbulence channels is analyzed. The purpose of the paper is: (i) to determine the channel capacity of FSO system in the presence of atmospheric turbulence, (ii) to see how much this limit can be approached using the best known STBC techniques. In this paper, we use mathematics tool to establish the channel model of FSO system, and then apply the STBC to the FSO system, research the decoding method and simulate the performance using MATLAB tools. The mathematics analysis and simulation results show the great application expectation of STBC in the OOK channel of the FSO system.
