Sequential symbol synchronizers based on pulse comparation at Half Rate

This work presents a synchronizer based on pulse comparation, between variable and fixed pulses. We consider four synchronizers, divided in two variants, one variant operate at the rate and the other at half rate. Each synchronizer variant has two versions which are the manual and the automatic. The objective is to study the synchronizers and evaluate the output jitter UIRMS (Unit Interval Root Mean Square) versus the input SNR (Signal Noise Ratio)

Prefilter bandwidth effects in sequential symbol synchronizers based on pulse comparation at half rate

This work studies the effects of the prefilter bandwidth in the sequential symbol synchronizers based on pulse comparation at half rate.We consider three different prefilter bandwidth namely B1=•, B2=2.tx and B3=1.tx, where tx is the bit rate.We consider also four synchronizers, where two operate at the rate with versions manual (b-m) and automatic (b-a) and two operate at half rate with versions manual (b-m/2) and automatic (b-a/2).The objective is to study the synchronizers and evaluate the output jitter UIRMS (Unit Interval Root Mean Square) versus the input SNR (Signal Noise Ratio)

Prefilter bandwidth effects on the sequential symbol synchronizers based on pulse comparation

This work presents a sequential symbol synchronizer, that is based on a comparation between variable pulse against a reference fixed pulse. This synchronizer has two types, namely the both data transitions and the positive data transitions. Each type has two versions: the manual and the automatic. Then, we apply a prefilter, with three bandwidths B, namely (B1=∞, B2=2.tx, B3=1.tx) to see its effects. Where tx is the bit rate. The objective is to study the synchronizers with the prefilter and evaluate the jitter UIRMS (Unit Interval Root Mean Square) versus the SNR (Signal Noise Ratio)
