Title: Finger tracking circuit for rake receiver
Inventor: LI GUANG Y
IPC: H04W56/00
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a means which quickly tracks a synchronizing signal in spread spectrum communication. SOLUTION: This finger tracking circuit 200 adapts a gain signal to a synchronizing error circuit as a function of the data rate of a carrier signal and SNR (S/N). Therefore, the convergence rate of the finger tracking circuit 200 indirectly depends on the intensity of the carrier signal (having a correlation to SNR of the carrier signal). Consequently, convergence is quickly performed when the data rate of the carrier signal is high. In an example, this finger tracking circuit 200 takes a form of a phase lock loop(PLL) for the purpose continuously tracking the carrier signal.
