“…4. As may be observed from the figure, the ACFs observed at t 1 and t 2 match each other, indicating that both H AB (f m , t) and H BA (f m , t) are WSS random processes, which is consistent with the simulation results in [23].…”

“…Under this assumption, we have already shown in [23] that OFDM subcarrier's channel response is a WSS random process. As a random process satisfies WSS property, data sampled by the same period will have the same correlation relationship.…”

“…The authors in [13] randomly select some key bits from the key streams generated from all the subcarriers and validate if the selected keys are the same at both users, which quickly becomes very inefficient whenever there are poor channel conditions, as a single key bit mismatch will result in a restart of the entire recombination process. We have proposed to generate keys from the channel responses of individual subcarriers in orthogonal frequencydivision multiplexing (OFDM) systems, using a statistical channel model [23]. We have proved that channel response of individual OFDM subcarrier is usually a wide sense stationary (WSS) random process, which allows us to find the optimal probing period and maximize the KGR.…”

“…[2] The Broadcast nature of wireless communications allows all the users within range to hear the transmission, thus making it vulnerable to various active and passive attacks. Wireless network security and privacy thus has attracted many research interests [3,6] Inter-satellite Optical wireless communication (IsOWC) is a capable solution for very high data rate point to point communication. With the rising popularity of high definition television and video conferencing, the demand for both high speeds wired and wireless access is continuously increasing in indoor and outdoor environments.…”

Inter-satellite optical-wireless communication systems (IsOWC), one of the important applications of FSO/WSO technology, will be deployed in space in the near future. The IsOWC systems provide a high bandwidth, small size, light weight, low power and low cost alternative to present microwave satellite systems. In this paper we have reported the challenges of Is-OWC Key words: Is-OWC (inter-satellite optical wireless communication), LOS (line of sight), I.INTRODUCTION Inter-satellite optical wireless communication has attained recognition in small time due to its infinite advantages as compared to its RF counterpart. This study includes system description of Is-OWC system with study of different parameters which effects system performance along with applications and advantages of utilizing this technology. Now we are in the twenty first century, the era of 'Information technology'. There is no doubt that information technology has had an exponential growth through the modern telecommunication systems. A communication system transmits information from one place to another, whether separated by a few kilometers or by transoceanic distances. Information is often carried by an electromagnetic carrier wave whose frequency can vary from a few megahertz to several hundred terahertzes. Optical communication systems use high carrier frequencies (100 THz) in the visible or near-infrared region of the electromagnetic spectrum. Fiber-optic communication systems are light wave systems that employ optical fibers for information transmission. One key problem for developing practical optical communications systems was the lack of good transmission medium.[1] Fig. 1 shows inter-satellite communication and optical communication.
