maximum likelihood detection.
The optimal detection threshold is obtained using the maximum likelihood detection scheme.
However, maximum parsimony detection results with a single classification.
Yet, despite its discovery as early as 1880, by the French scientists Jacques and Pierre Curie, and its World War I use by a fellow French physicist, Paul Langevin, in developing a sonar submarine detection device, piezoelectric technology has never been widely exploited.
LFM signal is a kind of classical non-stationary signal, which is widely used in radar, sonar, seismic detection, and so on.
