To solve the problem of identifying the alterable length frames, a specific frame synchronization algorithm is proposed in this paper. In the novel frame synchronization algorithm, the alterable length frames are demarcated by searching and checking the Attached Synchronization Marker bit by bit based on the altered frame format. Then the relevant performance parameters are analyzed and educed. The reference values for the rear protect time and the ahead protect time are given to ensure the probability of frame synchronization. Finally, the simulation results show that the novel frame synchronization algorithm can ensure the reliability of data transmitting and data processing for the adaptive frame length system.
