A novel hybrid optical code division multiple access in free space optical communication

摘要

Free space optical (FSO) communication is becoming a mainstream technology that plays a major role in application network. This system contains a techniques to reduce the probability of error. This paper focus on the performance Zero-Cross Correlation (ZCC) code of Optical Code Division Multiple Access (OCDMA) operation in FSO system. This paper also discuss about the comparison between ZCC code and OOC code. Result shows that ZCC code make a better performance than the conventional code between users and enhances the performance of FSO system based on the analysis of BER performance considering the avalanche (APD) noise, thermal noise and multiuser interference.
