A matched filter is an ideal filter which acts upon a received signal so as to maximize its signal to noise ratio (SNR). Under conditions of additive white Gaussian noise, the SNR is maximized when the impulse response of the receiver filter is an exact copy of the transmitted waveform (but reversed and time delayed).
