摘要
Abstract
In-depth research was carried out into parameters design in the feedback timing recovery loop based on Gardner timing error detector,according to the theory of digital phase-lock loop. MATLAB based simulation was performed for both first-order and second-order loop. Comprehensive analysis of the influence from loop order and noise- equivalent bandwidth on synchronization performance indicates the relationship between synchronization performance and noise-equivalent bandwidth,which provides a theoretic reference for timing recovery loop design.关键词
