Multi-Channel Transmission of Signal using Optical Wireless Communication (OWC) Channel : Channel Diversity Using OWC

Abstract

Optical Wireless Communication (OWC) channel is for inter-satellite communication. It is used as a subsystem of two telescopes or the wireless communication between two satellites. It is best suited for the modeling of satellite-satellite and earth-satellite links. The OWC channels are used for zero attenuation loss caused by atmospheric effects and no propagation delay Signal propagation delay. In this paper we basically deal with the designing of OWC link system. Further, comparative study has been made to ascertain which modulation technique proves better for communication. This paper investigates the transmission of signal through multiple number of OWC channel for better transmission of signal and better use of channel bandwidth. It also shows that as the channel diversity increase the efficiency of the system and thereby decreasing bit error rate (BER).The BER for different numbers of channels and get the accurate result at the receiver side with the high Q factor, accurate eye diagram and high data rate with proper signal and minimum bit error rate and result is shown in BER analyzer.
