度得到提高的正确性和可行性。采用System View 软件仿真实验验证了基于FFT 算法的GPS 伪码的快速

捕获新方法理论的正确性, 得出新码捕获方法较传统的码捕获方法得到捕获速度提高的结论, 为GPS 接收机适应高动态环境做了理论探讨。-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.
