Frame Synchronization Method for Adaptive Frame Length System

Aiming at the difficult for identifying the alterable length frames, a specific method of frame synchronization is proposed to solve the problem of frame synchronization for the adaptive frame length system. In the novel method, the core innovation about new frame format has been done. Based on the new frame format, the alterable length frames are demarcated by searching Frame Synchronization Header bit by bit and checking Frame Synchronization Header frame by frame. Then the relevant performance parameters are analyzed and educed. Finally, a simulation system is designed to verify the proposed method. By simulating, the reference values for the rear protect time and the ahead protect time are given to ensure the probability of frame synchronization method. The significance of solving the problem is to ensure the reliability of data transmission and processing for the adaptive frame length system. Compared with previous work, the novel method can enter the frame synchronization more easily.
