Investigation on the performance of 10 Gb/s on uplink space optical communication system based on MSK scheme

As the technique of space optical communication is developing, the requirement of higher data rate has attracted more attention. Currently, low data rate has been successfully applied in communication system. The next generation for space optical system have goal of higher data rate of 10Gb/s. In this paper, bit error rate (BER) performance on minimum shift keying (MSK) scheme at 10Gb/s data rate in uplink of space optical communication system is analyzed. From simulation results, probability density function (PDF) of received optical power shows left shift with increase of divergence angle at 10Gb/s data rate. Besides, we can increase ratio of receiving diameter and transmission diameter or decrease ratio of zenith angle and transmission diameter for better communication quality. These results are helpful for comprehending characters of the uplink optical communication system at 10Gb/s and the design of communication system.
