Abstract:

Optical wireless communication is getting attention due to edge over radio frequency communication in terms of bandwidth, data rate, security, EMI interference and unlicensed operations. In this work, a mode division multiplexed inter-satellite optical wireless communication is presented at different data rates such as 10 Gbps, 20 Gbps and 40 Gbps in terms of Q factor. Proposed work is accentuated towards the performance evaluation of modified differential phase shift keying (MD-DQPSK) modulation at different distances (750 km to 3750 km). Linear polarized (LP) modes, 64 in number are incorporated in the system to carry the high speed data. Further performance of proposed MD-DQPSK-MDM inter-satellite optical wireless communication is compared with differential quadrature phase shift keying (DQPSK), and Manchester coding and differential phase shift keying (DPSK). Q factor of MDRZ- DQPSK, DPSK, DQPSK and Manchester coding at 2500 km of link distance are observed as 16, 8.4, 10.37, and 3.56 respectively at 40 Gbps. Results revealed MD-DQPSK provide highest Q factor as compared to DQPSK, DPSK and Manchester modulation.
