Abstract:
Abstract- This work studies the effects of the prefilter bandwidth before the sequential symbol synchronizers based on pulse comparation at quarter rate. We consider three prefilter bandwidth namely B1=¥, B2=2.tx and B3=1.tx, where tx is the bit rate. We consider four synchronizers, one variant operates at the rate with versions manual (b-m) and automatic (b-a) and the other operates at quarter rate with versions manual (b-m/4) and automatic (b-a/4). The objective is to study the prefilter with the synchronizers and evaluate the output jitter UIRMS (Unit Interval Root Mean Square) versus input SNR (Signal Noise Ratio).
