circular convolution without cconv
显示 更早的评论
I have 2 vecrors of periodic coeffecients a_k , b_k. both of them size 2001 , start from 1 to 2001. 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 appreciate the help!

HI Liron,
One can do circular convolution by means of the fft, and there is plenty of information on the web about that.
