Abstract: Operation of discrete convolution and discrete correlation will spend too much time to process a signal in time. Aimed at this deficiency , a fast operating method of discrete convolution and correlation is presented in this paper. Computer simulation is carried out and satisfying results are obtained.
Key words: simulation;discrete convolution;discrete correlation, fast fourier transform(FFT)
摘要： 时域离散卷积和相关运算一般耗时太长,对信号进行处理的实时性较差.笔者提出了运用快速傅立叶变换(FFT)进行快速卷积和相关计算的方法.结合实际问题,取得令人满意的仿真效果.
关键词: 仿真, 离散卷积, 相关运算, 快速傅立叶变换
