  abstract = {The paper addresses the modeling and performance analysis of discrete delay-locked loop (DLL) code tracking for quadrature-spread direct-sequence code division multiple access (CDMA) signals (used in 3G UMTS) over Rayleigh fading channels. A discrete-time stochastic difference equation is derived to model the DLL tracking error dynamics as a firstorder Markovian process. The stationary probability density function of the tracking error is derivediteratively by solving a Kolmogorov-Chapman integral equation. Numerical examples with different system loading assumptions show that the proposed technique, while having a moderate computational complexity, produces much more accurate results when compared to simplified approximations based on Gaussian models for the DLL tracking error.},
