Abstract :
We propose a new PN chip clock generator which employs two synchronous counters to achieve precise control of chip clock in a CDMA code acquisition and code tracking. The proposed clock generator provides a reliable clock without any glitch. Since the chip clock generator can be easily controlled into one of the states: free running, phase advance and phase delay, it can be used for both data processing and code synchronization
