Real-Time Variance Calculation Method for Synchronous System Clock Based on Adaptive Exponential Smoothing

Abstract:

An adaptive clock variance calculation algorithm is designed to improve the real-time characteristics and complexity of general method. This algorithm use the latency and smoothing characteristics of exponential smoothing to achieve real-time calculation online. Using this algorithm, synchronous system can response to environmental changes in a short time. The test result shows that the real-time characteristics and output robustness can be improved obviously.
