摘要

符号同步器恢复时钟,然后用它对数据进行采样和重新计时。我们提出了两种同步器,第一种是基于带载波锁相环(CPLL)的滤波器,第二种是基于符号锁相环(SPLL)。每组有四种原型,即模拟型、混合型、组合型和顺序型。目的是研究各种同步器输出抖动UIRMS(单位间隔均方根)作为输入信噪比(信噪比)的函数。

Synchronizers based on carrier phase lock Loop and on symbol phase lock loop
The symbol synchronizer recoveries the clock and after, with it, samples and retimes the data. We present two synchronizer groups, the first based on filter with carrier phase lock loop (CPLL) and the second based on symbol phase lock loop (SPLL). Each group has four prototypes namely the analog, the hybrid, the combinational and the sequential. The objective is to study the various synchronizers output jitter UIRMS (unit interval root mean squared) as function of the input SNR (Signal to Noise Ratio).
