Analysis and Simulation on Measurement Error of PLL Loop

摘要

In receiver design, how to select the frequency discriminator loop the loop filter carrier tracking loop is critical. Due to the Doppler frequency difference uncertainty exists, the carrier phase direct capture a greater degree of difficulty, but was able to capture the frequency quickly eliminate most of the effects of the Doppler shift, and then the tracking phase is relatively easy to get many. Based on this idea, this paper, the performance FLL loop analysis and simulation.
