Are matched filter and correlator the same communication device?

They are different devices (one is indeed a filter and the other is a multiplier followed by an integrator) and the waveforms in their outputs are usually different from one another, but at the best sampling instant, and only in this instant, the measured SNRs are the same in both.

What is a cascading filter?

Cascading filters are filters that let you drill into a specific selection to decide what to include or exclude. The multi-select means an end user can choose items in different groupings of the date; for example multiple sub-categories across different categories.

How does matched filter increase SNR?

The matched filter improves the SNR by reducing the noise's spectral bandwidth to that of the wavelet, and in addition, reduces the noise within the wavelet's bandwidth by the shape of the wavelet's spectrum.

What type of filter is matched filter?

Matched filters are commonly used in radar, in which a known signal is sent out, and the reflected signal is examined for common elements of the out-going signal. Pulse compression is an example of matched filtering. It is so called because the impulse response is matched to input pulse signals.
