Abstract(s)

This work studies the effects of the prefilter bandwidth on the carrier phase synchronizers. We apply three different prefilter bandwidth namely B1=¥ (infinite), B2=2.tx and B3=1.tx, where tx is the transmissionrate. We consider also four carrier wave phase synchronizers namely the analog (ana), the hybrid (hib), the combinational (cmb) and the sequential (seq). The objective is to study the prefilter bandwidth with the four carrier synchronizers and to evaluate their output jitter UIRMS (Unit Interval Root Mean Square) versus input SNR (Signal to Noise Ratio).
