Abstract

In this work, we report the designing and simulative analysis of a novel 400 Gbps coherent detection-orthogonal frequency division multiplexing (CO-OFDM) based inter-satellite optical wireless communication (IsOWC) system incorporating polarization division multiplexing (PDM) for enhancing information carrying capacity of the link. The performance of the proposed system has been discussed for 4-level phase shift keying and quadrature amplitude modulation encoding schemes using signal-to-noise ratio, total received power, and constellation diagram of the received signal as performance metrics. Also, the impact of different parameters such as operating wavelength, transmission power, and receiver pointing error angle on the performance of the proposed system has been investigated. Furthermore, an enhanced detection technique for link reach enhancement has been reported in this work. Finally, the performance of the proposed CO-OFDM based IsOWC system has been compared for with and without using the PDM technique.
