What is a matched filter in digital communication?
The matched filter is the optimal linear filter for maximizing the signal-to-noise ratio (SNR) in the presence of additive stochastic noise. 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.
What is matched filter detection?
2 Matched filter detection method. The matched filter (MF) technique is an optimum method to sense availability of spectrum since the MF can maximize the SNR even if there is additive white Gaussian noise (AWGN). This feature is accomplished via correlation process inherent of the method.
What are the characteristics of matched filter?
If a filter produces an output in such a way that it maximizes the ratio of output peak power to mean noise power in its frequency response, then that filter is called Matched filter. This is an important criterion, which is considered while designing any Radar receiver.
What is matched filtering in image processing?
A matched filter is a linear filter with a transfer function that maximizes the output signal-to-noise ratio (SNR) for an input signal with known properties.
