Hi guys, Im processing an signal FM with noise that I enter this mixed signal to matched filter in order to detect my FM signal, Im trying to find out and figure how the size of matched filter is related to my FFT of the input signal .. could any one help me to understand well how the size of matched filter affected on my FFT signal? I mean what's the relation between the size of my matched filter (size of vector of specific frequency that Im looking for) to my FFT signal , thanks alot !
