Patent ID: 7529292

Claim:
A user equipment (UE), comprising: a receiver for receiving a communication signal from at least one base station; and a delay-locked code tracking loop (DCTL) for estimating and tracking a channel delay of said received communication signal, the DCTL comprising: a reference code generator for generating a reference code signal; an interpolator for generating a punctual output signal, an early output signal and a late output signal; a first timed signal correlator for correlating said early output signal with said reference code signal to generate a first correlated signal; a second timed signal correlator for correlating said late output signal with said reference code signal to generate a second correlated signal; a third timed signal correlator for correlating said punctual output signal with said reference code signal to generate a third correlated signal; an adder for combining the first and second correlated signals to generate a first error signal; an automatic power normalization (APN) loop for generating a second error signal based on said third correlated signal; and a normalization circuit for normalizing said first error signal by using said second error signal to generate a third error signal used for controlling the generation of the punctual output signal by the interpolator.
