1. 定义与概念 圆周卷积也叫循环卷积, 2. 实现(matlab) 以圆周的形式卷积两个信号: >> z = ifft(fft(x).*fft(y)); 1.
The overlap–add method is an efficient way to evaluate the discrete convolution of a very long signal with a finite impulse response (FIR) filter where h[m] = 0 for m outside the region [1, M].The concept here is to divide the problem into multiple convolutions of h[n] with...

圆周卷积(circular convolution) 1. 定义与概念 圆周卷积也叫循环卷积, 2. 实现(matlab) 以圆周的形式卷积两个信号: >> z = ifft(fft(x).*fft(y)); 1.
Inside of your anonymous function, you could use logical indexing to only apply the operation to the circular part of the rectangular. As for generating the circle, an easy way:
I need to make circular convolution between them without using cconv. The formula: f_k = (l=(-1000,1000))a_l*b_k-l N=2001; l is vector (-1000:1:1000); I don't know how to write this in Matlab without using cconv func..(also better without for loops). I realy ...
