Performance Investigation Of CPFSK integrated with OFDM in Inter-satellite OWC System

Abstract

Inter-satellite optical wireless communication (IsOWC) uses light technology which makes it feasible to achieve long haul communication at high data rate. In this paper, the proposed work is aimed to achieve a high speed long haul communication by using continuous phase frequency shift keying modulation technique in combination with orthogonal frequency division multiplexing in IsOWC. The system’s performance is investigated in terms of received power and Q-factor for different transmission ranges and bit rate values. It is observed that the system can successfully transmit the 10 Gbps data stream over a range of 8000 km with high value of received power and an acceptable value of Q-factor.
