The chapter introduces to the basic concepts and definitions, which form the basis of timing and synchronization in telecom. In particular, the timing signal model and specifications, basic relations between frequency and phase, time scales alignment, the main metrics used for synchronization quality evaluation (TIE- and PDV- based metrics), and the phase distortions (jitter/wander, noises) are considered. All these issues are further developed in the next chapters.

摘要

The chapter introduces to the basic concepts and definitions, which form the basis of timing and synchronization in telecom. In particular, the timing signal model and specifications, basic relations between frequency and phase, time scales alignment, the main metrics used for synchronization quality evaluation (TIE- and PDV- based metrics), and the phase distortions (jitter/wander, noises) are considered. All these issues are further developed in the next chapters.
