The generation of synchronous signals is usually achieved through frequency division, but it is not flexible enough and the design is complex. This article adopts a ROM based table lookup method, which is simple, flexible, and has strong practicality. In order to improve the reliability and anti-interference ability of frame synchronization system synchronization establishment, frame synchronization circuits need to adopt certain protective measures. The usual approach is to divide the working state of frame synchronization into capture state and tracking state. Adaptive switching of the threshold for frame header decision in capture and tracking states. This article further improves system performance by using methods such as capture and out of step quadratic threshold judgment, single frame/subframe parallel detection, and frame correction. The second threshold decision is to increase the confidence level of the capture or out of step event when it occurs, and only when a certain value is reached, it is recognized that the capture or out of step event has occurred, which has strong protection ability for the frame synchronization circuit. Single frame/subframe parallel detection can reduce re capture due to single frame or subframe loss, and improve the speed of out of step re capture. For the loss of positive synchronization code groups within the fault tolerance range, the system’s pseudo out of step discrimination ability can be improved through frame correction processing. The frame synchronization system should have a short synchronization establishment time, and out of step, it can catch faster; Strong anti-interference ability, namely the ability to identify false out of step and avoid false synchronization; Long synchronization retention time and low probability of out of step. The performance of frame synchronization systems is usually measured by the probability of missed synchronization, false synchronization probability, and frame synchronization establishment time
