In this report, we discuss the physics of fading and summarize the methods to mitigate its devastating effects for communication channels. We evaluation 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 rations by using simulation curves to assess link margins for the UHF Follow-On Satellite.
