Techniques to acquire and track pilots in a CDMA system. In an aspect,
frequency acquisition of a number of signal instances (i.e., multipaths)
in a received signal may be achieved concurrently based on a frequency
control loop (RAFC) maintained for each finger processor of a rake
receiver. Upon successful acquisition, frequency tracking of acquired
multipaths may be achieved based on a combination of a frequency control
loop (VAFC) maintained for an oscillator used for downconverting the
received signal and the RAFCs for the finger processors. In a tracking
mode, the VAFC tracks the average frequency of the acquired multipaths by
adjusting the frequency of the oscillator. The RAFC of each finger
processor tracks the residual frequency error (e.g., due to Doppler
frequency shift) of the individual acquired multipath by adjusting the
frequency of a complex sinusoidal signal used in a rotator within the
finger processor.
