摘要
文章提出了一种ADSL系统中基于离散多音调制解调结构的时钟同步方法。该方法根据锁相环的原理,充分利用了系统的现有结构,不需要专用的锁相环,降低了系统复杂度。实验结果显示,该方法精度高,自适应和抗干扰能力强。
A clock synchronization method used in ADSL systems based on Discrete Multitone(DMT) is presented. According to the phase-locking theory, clock synchronization is implemented using digital method based on the DMT structure. In this method, no special phase-locking loop is needed, so the implementing complexity is decreased. Practical examples show this method has a high precision and the ability of auto-adaptation and anti-jamming is good.
