Performance Improvement in Inter-satellite Optical Wireless Communication to Mitigate Losses Using Diversity Technique

The superior network quality with highest speed and lowest cost is the requirement of the next-generation wireless communication system. Many technologies came into existence, which we have experienced in various applications. Establishment of network between satellites using optical wireless communication is a promising solution to achieve successful communication goal. In this paper, we have designed and simulated inter-satellite optical link using diversity technique to achieve the bit-rate of 30 Gbps for the pointing error of 1.1 µrad and additional losses of 3 dB. The proposed system is analyzed on the basis of performance parameters such as quality factor, BER, and eye diagram obtained. The proposed system will be advantageous to fulfill the needs of next-generation system.
