摘要:
通过对循环平稳检测算法的分析,对基于SSCA算法的FFT模块进行设计并验证时序。首先,对循环平稳检测算法进行了研究与仿真,比较了现存的几种循环平稳检测方法的复杂度。其次,选择SSCA算法,提出了一种流水线工作方式的定常构形FFT模块的设计方案。最后,在开发环境QuartusⅡ进行模块的构建,在仿真软件ModelSim环境下进行时序验证,从而实现了算法硬件化。

Abstract:
Through analysis of smooth loop demodulation algorithm,we design and verify the timing of FFT module based on SSCA. Firstly,we analyze and simulate the smooth loop demodulation algorithms and then compare the complexities of two existing smooth loop demodulation algorithms. Secondly,we select the SSCA algorithm,and put forward a set of assembly line work regular constant shape FFT module design schemes. Finally,we build the module in the Quartus Π and verify the timing under the ModelSim environment so as to implement the algorithm of hardware; thus,we believe that our design is effective.
