Abstract-The evolution of optical communications systems from long fibers to robust wireless system has led to the idea of connecting two satellites using an optical wireless link. The rapid developments in satellite communication point to the possibilities of satellite networks as a method for them to communicate with each other. The optical wireless communication (OWC) enables the information exchange between satellites at higher speed and also a satellite can act as a relay between two satellites or between a satellite and ground base station. Light signal of high frequency is used as a carrier for the optical link between satellites and lasers are commonly used as a source of light. One of the primary reasons for preferring OWC over RF link is high data rate with acceptable bit error rate (BER). The communication between two lower earth orbit (LEO) satellites is studied under this research work. The quality factor (Q-factor) or BER is used as a key metric to analyze the performance of the inter-satellite link (ISL). This work presents the performance enhancement of the system by using multiple antennas and advanced modulation techniques.

“…The transmitting antenna sends mass data to the receiving antenna via a wireless satellite channel. The main influencing factor of channel fading is free space loss [24]. In this paper, For the satellite channel, we describe the impairment process as Rayleigh fading channel with a fixed threshold ξ.…”

To meet the growth of real-time and multimedia traffic, the next generation of satellite networks with a guarantee of quality of service (QoS) is indeed, urgent. In this paper, we support the multi-layered satellite network as the scenario, owing to dynamic topology and distinct classification of the generated traffics. We map the satellite network system into a tandem queuing model, which the purpose is devoted to use a mathematical tool for evaluating the performance bounds of per-flow end-to-end networks. For delay-sensitive traffics, we compare two different arrival models-Poisson process and self-similar process. Meanwhile, we apply traditional scheduling strategy to MEO nodes while considering link impairment between a pair of satellites. Finally, we analyze, in a numerically way, which parameters (and how they) influence the perflow end-to-end performance bounds. Our analysis can be used as a reference to China's future satellite topology and routing algorithms designed and, optimization given a network with performance requirements and constraints.

“…Another study proposed the design of an ultra-high bit-rate (400 Gbps) inter-satellite optical wireless communication (IsOWC) system which was a non-diffused link used for quadrature phase-shift keying (QPSK) modulation [14]. The study examined the system performance, with various parameters such as Q-factor, eye opening, and bit-error rate, while observing coverage distance of 30 dBm input power at the bit rates of 400 Gbps/4767 Km, 160 Gbps/7542 Km, and 100 Gbps/9532 Km.…”
