Secure Optical Wireless Satellite Network based OWC-OCDM System with DDW code

Data security with high transmission rate is one of major concern in these days especially for multiple users. An optical wireless satellite network basis optical wireless communication (OWC) with optical code division multiplexing (OCDM) system is proposed. Diagonal double weight (DDW) code is employed to enhance the system security and cost effectiveness with minimum channel interference. The obtained simulation results revealed the maximum bidirectional transmission range of the system of 8000km at 20Gbps per link traffic rate. The traffic rate can be improved upto maximum 90Gbps over 5000km range. Also, the system employing DDW code can handle upto 340 satellite links simultaneously. Besides this, the model comparison with others shows its optimum performance over other for various satellite applications.
