High Speed and Long Reach DPSK-OFDM-Is-OWC under Impact of Space Turbulences

Abstract

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).

High Speed RGB-Based Duobinary-Encoded Visible Light Communication System Under the Impact of Turbulences

“…Optics in a wireless fashion (also known as optical wireless communication) garnered the attention of researchers in early 2010 and have been widely deployed for communication. Key works of optics in wireless communication are divided primarily into three sections including Inter-satellite Optical Wireless Communication [4][5][6][7][8][9][10][11][12] and Free space Optics (FSO) [5,[13][14][15][16][17][18][19][20][21][22][23][24]. Free Space optics have been widely deployed in providing high speed and secure communication where a wired system is a costly [25][26][27][28].…”
