高速数据通讯系统的定时恢复方案

A Timing Recovery Scheme for High Speed Data Transmission Systems

用一个允许使用全数字锁相环的比特率采样方法 ,提出数据传输系统的定时恢复方案 ,并在 ETSI(European Telecommunications Standardization Institute)的 HDSL标准环境下讨论数字控制振荡器对信噪比和抖动的影响 .

A timing recovery scheme for high speed data transmission systems was given by using a bit rate sampling method allowing to adopt all numerically phase locked loop. In addition, the impact of a numericlly controlled oscillator on the attainable signal to noise ratio and jitter under the conditions of HDSL standard of ETSI is discussed.
