Abstract :
An open-loop, passive, master-slave, global synchronization system that is Earth terminal based is proposed for a processing satellite communication system. Symbol timing recovery techniques for global synchronization are studied by both analysis and computer simulation. A Markov chain model is used to analyze the synchronizer. The analysis of bit error rate (BER) on both the downlink and the uplink of the processing satellite system shows that timing jitter caused by random noise and clock frequency offset will degrade the system performance from perfect timing by about 0.5 dB at a BER of 10-5. Also the estimated error of five percent in the propagation delay in the uplink causes a further 1 dB loss
