International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / FLL’s are extensively used for fast carrier synchronization. A common approach to meet the
wide acquisition range and sufficiently small tracking error requirements is to adopt the wide
or narrow band FLL loop in the acquisition and tracking modes and direct switching the loop.
The paper analyze the influence of direct switching on performance, including the narrow
band loop convergence, transition time etc. and propose applying the Kalman filtering theory
to realize the seamless switching (SS) with time-varying loop gains between the two different
loop tracking state. The SS control gains for the high dynamic digital spread spectrum
receiver is derived. Simulation results for the SS compared to the direct switching
demonstrate the improved performance.
