FFT algorithm in the analysis is based on fast acquisition GPS PN code based on the new method, through the traditional two-dimensional time-domain code acquisition method and the serial FFT algorithm based on GPS pseudo-code the new method of capturing the number of operations needed to compare demonstrated a new method in theory, pseudo-code acquisition speed is improved accuracy and feasibility. Using System View software simulation results verify the FFT algorithm based fast acquisition GPS PN accuracy of new method to generate new code acquisition method than the traditional method of code acquisition speed to capture the conclusions obtained for the GPS receiver to adapt to high Theory of dynamic environment do.
