Abstract (en)
[origin: EP0620546A2] The energy detection procedure for useful signals embedded in noise, consists, according to the invention, starting from a frame of samples of a noisy signal, grouped into successive frames, in performing a preclassification by comparing the energies of the successive samples of each frame with a specified optimal threshold and in classing into a first "noise only" class the samples which exhibit a high probability of belonging to this class, and then, for each of these samples, those exhibiting a sufficiently high energy for their probability of belonging to a second "noise + useful signal" class to be high are detected, this second class being defined by taking the first class as reference.
