Communication has become a utility like electricity and water. With the advancement in the technology, needs of users, services, demands have been increasing day by day. So it requires high bandwidth, higher data rates, and better reliability. So for these reasons optical fibers have been used. Optical communication has advanced from long strands to wireless technology. This has resulted to use the optical communication in space. Inter-Satellite communication is one among them. Large numbers of satellites are revolving around the Earth. So a network is required which can hand-off data from one satellite to another and afterwards to the ground station. Inter-Satellite communication is one of the remarkable technologies. In this paper, inter-satellite optical wireless communication system (Is-OWC) is analyzed using different modulation techniques and formats. Various specifications such as bit error rate, Q factor, and input power are studied.

The Radio Over Fiber technology is an enhanced form of wireless communication. But this also suffers from various issues such as limited number of users, introduction to noise in signals, unwanted frequencies, low quality of signals due to noise etc. Therefore, the objective of this study is to design such a RoF communication system which can accomplish communication by using multiple users and also filter the noise from the signals to enhance the quality of the signals. This study has been conducted with an objective to implement the best of the modulation on communication system and results are analyzed on three different systems with different form of filtration techniques i.e. Low Pass Bessel, Low Pass Gaussian Filters and low Pass Rectangular Filters. The disadvantage of earlier system was that it did not supports more than one users at a time therefore the proposed work also facilitates to perform communication by using 8×8 transmitters and receivers. The model is designed by using Opti-system. The result section depicts the proficiency of proposed model.

“…These satellites may be orbiting in the same or in different orbit. At receiving satellites, received signal are demodulated using photodiodes and thus original signal is recovered [4][5][6][7]. In OWC, Orthogonal Frequency Division Multiplexing (OFDM) technology has played an vital role for it capacity in reducing multipath fading effects [8][9][10][11][12][13][14][15][16].…”

“…Though the vacuum is assumed to be perfect, path loss which increases as square f the distance is huge. Further Is-OWC links are sensitive for pointing errors which may arise due to misalignment, vibrations or tracking errors [22][23][24][25][26][27][28][29][30][31][32][33][34][35] [2][3][4][5][6][7][8][9][10][11][12]. In our work OFDM-DPSK-Is-OWC system is designed to transmit 10 Gbps data over a distance of 10,000 Km under the impact of turbulence.…”

Inter-satellite communication is a free-space optical technology which is used to establish communication between satellites in space. This work is focused on the transmission of 10 Gbps data over 10,000 km inter-satellite communication link by incorporating orthogonal frequency division multiplexing scheme. The performance of proposed system is evaluated in terms of signal-to-noise ratio, total received power, radio-frequency spectrum and constellation diagrams. KeywordsInter-satellite communication (Is-OWC), Orthogonal frequency division multiplexing (OFDM), Differential phase shift key (DPSK).
