正如卷积有线性卷积(linear convolution)和循环卷积(circular convolution)之分;互相关也有线性互相关(linear cross-correlation)和循环互相关(circular cross-correlation)。线性互相关和循环互相关的基本公式是一致的,不同之处在于如何处理边界数据。其本质的不同在于它们对原始数据的看法不同。通过这篇文章,我想整理一下...

it needs to draw up program code according to the operational course of circular convolution.FFT is the major operation of DSP ,when sequence grows fairly ,FF T is a kind of most suitable method ,it is more rapidly in opera 2tional speed and program simple ,the longer of the sequence ...
Perform discrete-time circular convolution by using toeplitz to form the circulant matrix for convolution. Define the periodic input x and the system response h. x = [1 8 3 2 5]; h = [3 5 2 4 1]; Form the column vector c to create a circulant matrix where length(c) = length(...
