<p>The UE is in communication with one of the plurality of base stations and receives a communication signal from the base station through the CDMA receiver. The communication signal is correlated by said receiver using a delay locked code tracking loop (10), that estimates and tracks a channel delay of the communication signal. The tracking loop comprises a reference code generator (16) for generating a reference code signal and an interpolator (11) for generating timed signal versions in response to the receipt of said communication. A timed signal correlator (12a, 12b, 13a; 13b), also included in the tracking loop for correlating at least two of the timed signal versions with the code reference signal. The result of the correlation is used for generating an error signal. An automatic power normalization loop (APN), that is responsive to the interpolator (11), generates a power error signal that normalizes the error signal through a normalization circuit (14).</p> |
