摘要
该文介绍了高效循环谱估计算法SSCA(Strip Spectral Correlation Algorithm)中FFT模块的重要作用,给出了一种FFT模块的设计和实现方案。该方案采用定常构形算法,可以很好地满足SSCA算法对FFT核心模块的并行化以及高速运算要求,同时数据处理采用流水线工作方式,大大提高了FFT模块的连续处理数据能力。仿真测试表明,该方案能够满足SSCA算法对FFT模块的运算要求。
This paper introduces the important key of FFT processor in the SSCA algorithms which is the high efficient algorithms in cyclic spectral analysises.To meet real-time processing and parallel operatio,this paper introduces a constant geometry FFT processor,and assembly line structure has been brought forward to increase the continuous computing capability of the FFT processor.The simulation and analysis of the whole system prove that it can meet the requirement of the SSCA algorithms.
