A New Rapid Acquisition and Tracking Technique for High-Dynamic Spread Spectrum Signals

According to the requirements of wireless access of spread spectrum signals under high-dynamic environments, this paper proposed an improved PMF (Partial Matched Filter)-FFT acquisition algorithm and a third-order phase-locked loop tracking algorithm. The validity of the algorithm with the merits of high performance and high probability of capture is proved by theoretical analysis and simulation results. It can be suitable for the applications of fast acquisition and stable tracking in high dynamic environments.
