Performance Evaluation of UHF Fading Satellite Channel by Simulation for Different Modulation Schemes

Abstract

In this report, we discuss the physics of fading and summarize the methods to mitigate its devastating effects for communication channels. We evaluated performance curves of Differentially Encoded Binary Phase Shift Keying (DBPSK) , Rate 1/2 Convolutionally Encoded Differential Quadrature Phase Shift Keying (DQPSK) and Minimum Shift Keying (MSK), by simulation for both AWGN and fading channels. Further, we simulated typical transponder components of a UHF satellite system and evaluated their effect for the above modulation structures. Finally, we calculated the carrier-to-noise ratios by using simulation curves to assess link margins for the UHF Follow-On Satellite.
