CIRCUIT AND METHOD FOR TRACKING FINGER OFF-SET IN A SPREAD-SPECTRUM RAKE RECEIVER AND WIRELESS INFRASTRUCTURE EMPLOYING THE SAME |
摘要 |
<p>A finger tracking circuit for a rake receiver, a method of tracking a carrier signal and a wireless infrastructure. The finger tracking circuit includes: (1) a timing error subcircuit that determines a timing error in a current power control group ("PCG") of a carrier signal to be tracked and (2) a feedback subcircuit that applies a gain signal that is a function of a data rate of the carrier signal and a signal-to-noise ratio ("SNR") to the timing error subcircuit, a convergence rate of the finger tracking circuit therefore depending on the data rate of the carrier signal.</p> |
