Probability of error of matched filter

Webbthat no receiver, whether using a linear lter or a nonlinear lter, can achieve an error probability smaller than P e. That is the least error probability that we can achieve with … When the output of the matched filter system exceeds a certain threshold, we conclude with high probability that the received signal has been reflected off the object. Using the speed of propagation and the time that we first observe the reflected signal, we can estimate the distance of the object. Visa mer In signal processing, a matched filter is obtained by correlating a known delayed signal, or template, with an unknown signal to detect the presence of the template in the unknown signal. This is equivalent to Visa mer Derivation via matrix algebra The following section derives the matched filter for a discrete-time system. The derivation for a Visa mer When viewed in the frequency domain, it is evident that the matched filter applies the greatest weighting to spectral components exhibiting the greatest signal-to-noise ratio (i.e., large weight where noise is relatively low, and vice versa). In general this requires … Visa mer • Turin, G. L. (1960). "An introduction to matched filters". IRE Transactions on Information Theory. 6 (3): 311–329. doi:10.1109/TIT.1960.1057571. • Wainstein, L.
