matched filter การใช้

• Matched filters play a central role in gravitational-wave astronomy.
• Time reversal techniques can be modeled as a matched filter.
• Receiver structure for QPSK . The matched filters can be replaced with correlators.
• The following section derives the matched filter for a discrete-time system.
• Matched filters are often used in signal detection.
• The matched filter is also used in communications.
• In general, the compression process is a practical implementation of a matched filter system.
• Additionally, matched filters can be used in parameter estimation problems ( see estimation theory ).
• Verdu's receiver consisted of a bank of matched filters followed by a Viterbi algorithm.
• An example filter is the matched filter which uses the cross correlation of the two signals.
• Matched filters perform a cross-correlation between the input signal and a known pulse-shape.
• Alternatively, we may solve for the matched filter by solving our maximization problem with a Lagrangian.
• The recorded signal will be processed using a matched filter to detect echos from discontinuities within the solid.
• To do so, we may correlate the received signal with several matched filters of sinusoids at varying frequencies.
• To increase our signal-to-noise ratio, we pass the received signal through a matched filter.
• This work on noise produced the concept, and led Zobel to pursue the design, of matched filters.
• Sender side pulse shaping is often combined with a receiver side matched filter to achieve optimum tolerance for noise in the system.
• The results of each run of the matched filter can be compared, the correct PSC being identified by the greatest correlation result.
• The appropriate h _ { j-k } will later turn out to be the matched filter, but is as yet unspecified.
• On the technical side, the matched filter is a " weighted least squares " method based on the ( whitened data.
