【摘要】 针对当前捕获的方式不能同时满足捕获速度快和硬件简单的问题,文中研究了一种基于 FFT 的并行捕获算法。该算法能够实现并行捕获,捕获速度快,同时避免了复杂的硬件设计。通过对串行捕获和 FFT 并行捕获方式的捕获进行仿真,结果表明了 FFT 并行捕获的合理性。更多还原

【Abstract】 Due to current search strategies can’t meet quite short acquisition time in simple hardware, this paper studies a algorithm of parallel acquisition FFT-based.This algorithm is capable of searching in parallel,so its acquisition time is quite short,and avoid designing complex hardware. Simulating for FFT-based parallel acquisition and sequential acquisition,the analysis and simulations show that algorithm of parallel acquisition FFT-based is simple,efficient and very fast in search time.更多还原
