Comparing Digital Phase-Locked Loop and Kalman Filter for Clock Tracking in Ultrawideband Location System

الملخص EN

For timing and synchronization system, digital phase-locked loop (DPLL) and Kalman filter all have been widely used as the clock tracking and clock correction schemes for the similar structure and properties.

This paper compares the two schemes used for ultrawideband (UWB) location system.

The improved Kalman filter is more immune to interference.
