Inter-satellite OWC Incorporated OCDMA System Employing Modified ZCC Code

Today, satellite communication is one of the most emerging communication media for broadcasting the different kinds of information to various users. The data security is one of the primary objectives in satellite communication. An inter-satellite high speed optical wireless communication (OWC) incorporated optical code division multiple access (OCDMA) system is proposed. Zero cross correlation (ZCC) code is used to enhance the system capacity and data security. From results it is noticed that faithful OWC range of 5000 km can at 20 Gbps channel rate is obtained successfully. The channel rate can be improved upto 200 Gbps over 1000km OWC. Also, the system offers maximum 16 dB signal to noise ratio for six users of ZCC code. As compared to multi-diagonal and random diagonal codes, ZCC code supports 45 to 65 users simultaneously for code weight of 2 to 4. The proposed model shows better performance over other inter-satellite models for long-haul high speed links.
