Matched filter using FFT
显示 更早的评论
hai
Ive a 2d array of 1536*1 double data, and I need to find the matched filter output with respect to the refference date v_tx of diamension 1536*1. This matched filtering is to be done with the help of FFT function.(I cannot use any in-build matlab functions) thanks in advance.
regards
Aleesha

Hi
Basicaly, you will need to multiply the FFT of the input signal by the FFT of the reference signal then IFFT the result of the multiplication.
Input ====> FFT ====> X ====> IFFT ====> Output
