The tracking accuracy of baseband Delay Locked Loop (DLL) with narrow loop band is studied. The equivalent phase discrimination model of code delay correlator is provided, and the correlation functions and power spectrum density functions of correlator output port noise and its equivalent noise at the input port are developed, then the simplified calculation equation of the tracking accuracy of linear...
In this paper, we examine controllability result for evolution inclusions with nonlocal condition. By using a recent fixed-point theorem due to Dhage, we establish sufficient condition of controllability.
The theoretical expression is presented in this study to predict the early minus late power (EMLP) code tracking performance with residual frequency shift and finite front-end bandwidth. On basis of the expression and numerical simulation, the impact on the code tacking performance of Doppler hopping caused by radio frequency hopping of DS/FH signal for TT&C as well as tracking system parameters...
