Matched filter is obtained by correlating a known signal, or template, with an unknown signal to detect the presence of the template in the unknown signal.

Understanding matched filter
I have a question about matched filtering. Does the matched filter maximise the SNR at the moment of decision only? As far as I understand, if you put, say, NRZ through a matched filter, the SNR ...

Match Filter in Time-Frequency domain instead of just Time domain. Redundant, or better?
Assume you have a signal, and within it, some pulses are present. A pulse is a simple tone. You know the pulses' duration, and shape. (Let us assume that a pulse is made of a couple of cycles, and ...

How do you calculate the gain of a matched filter?
I know that you can calculate the gain of a low-pass filter by summing the filter coefficients. I don't know how to calculate the gain of an arbitrary matched filter.
For instance, I have created a ...

Optimum matched filter without ISI
Given a filter used to shape the digital signal, $p(x)$, and given that we do not want the filter combination to cause any ISI, what "matched" filter, $q(x)$ will maximise the SNR?
Matched filters ...
