I have seen this question asked so many times but I couldn't find the required answer. Both matched filter and correlator seem to have the same expression. Matched filter seems to be implemented using filter while correlator can be done by mixing them and averaging. Both need synchronization for maximum SNR. But most of us prefer matched filter and I don't know why. Is there any specific advantage for this Matched Filter? Or is there anything like -" Matched filter is intended for some kind of systems and correlators are intended for some other kind of systems" ??
