In my recent work I have to use matched filtering (MF). I almost forgot most
of it that I learned in my class, so I am re-reading about it now, then had a
few questions. Here is a major one.
First I'd like to review the principle of MF in brief: it is used to maximize
the peak Signal-to-Noise ratio (SNR), at a certain sampling point, via addi | f****n
发帖数: 355 | 2 I almost forgot about it too. As I remember, T_m is just a time delay
which decide when you get maximum in the output. If you set T_m to
the signal length, you get maximum in the output exactly at when the
signal in the input starts. So for instance if you want to estimate
the time delay of a signal in the input, you do this.
