摘要
invention is a digital phase tracking loop (Phase-Locked Loop) or the frequency tracking loop (Frequency-Locked Loop ) relates to an apparatus and method for coherent phase jump in compensation, the external synchronizing signal (Reference signal) for detecting a phase difference of the two signals compared with the phase of the internal signal phase determination groups, the phase difference using a phase jump detecting the moment (jump moment detection), and, when the phase jumps are detected, evaluating the degree of the previous phase of the phase difference based on the current jump (Jump value estimation) and then, using the phase jump correction value obtained by evaluating the and by the phase jump compensator for correcting a phase difference, including the LPF (Low Pass Filter) to filter the high frequency components of the corrected phase difference, E1 / T1 there is an advantage that a stable synchronization can be implemented in the network synchronization.
