本文第一部份已就帧同步码检出的基本原理及固定相关电平判决帧同步检出电路进行了分析讨论。本文将就最大相关电平判决方式的帧同步检出电路进行分析讨论,比较二种检出电路的优缺点,提出电路设计应考虑的原则。
The first part of this paper has analyzed and discussed the basic principle of the frame synchronization code detection and the fixed correlation level decision frame synchronization detection circuit. This paper will analyze and discuss the frame synchronization detection circuit based on the maximum correlation level decision method. The advantages and disadvantages of the two detection circuits are compared and the principle of circuit design should be considered.
