For that purpose, tracking loops are used in a closed loop to follow continuously the code and carrier parameters of the incoming signal.
Results of implementation show performance of the loops. The tracking loop is carried out in MATLAB using samples of intermediate frequency signal recorded ...
There are code tracking loops, the delay lock loops (DLL) and carrier tracking loops, and the phase locking loops (PLL) in the receiver. Typically, both the code ...
Carrier phase estimation in real-time Global Navigation Satellite System (GNSS) receivers is usually performed by tracking loops due to their very low ...
The conventional phase-locked loop (PLL) has been widely used in the carrier tracking loop. The typical strategy for improving the PLL sensitivity ...
Constant-bandwidth loops with loop bandwidths near 15. Hz are shown to lose phase lock during scintillations. Use of the decision-directed discriminator reduces ...
The carrier tracking loop performs the task of aligning the local generated carrier with the incoming signal while the code tracking loop ensures ...
Design and Performance Evaluation of a Dual Antenna Joint Carrier Tracking Loop. Sensors (Basel). 2015 Oct 1;15(10):25399-415. doi: 10.3390/s151025399.
To obtain a better solution to this problem, an adaptive carrier tracking loop may be used. The loop normally operates using only the PLL portion with a tight ...
For global navigation satellite system receivers, Kalman filter (KF)-based tracking loops show remarkable advantages in terms of tracking ...
