Are PLLs dead? A tutorial on kalman filter-based techniques for digital carrier synchronization
IEEE Aerospace and Electronic Systems Magazine(2017)
摘要
Carrier synchronization is a fundamental stage in the receiver side of any communication or positioning system. Traditional carrier phase tracking techniques are based on well-known phase-locked loop (PLL) closed-loop architectures, which are still the methods of choice in modern receivers. Those techniques are well understood, easy to tune, and perform well under benign propagation conditions, bu...
