In this paper, using a linear characteristic of tan-1() function with in-phase and quadrature-phase samples, we propose a phase error tracking and correcting algorithm for demodulating QPSK-spread IS-95 signal. We derive the proposed algorithm and simulate the performance which shows that the proposed algorithm corrects the phase error between the transmitted and the received signals
