Abstract
The energy-based process according to the invention for the detection of useful signals drowned in noise consists of starting from a frame of samples of a noisy signal grouped in successive frames, making a pre-classification by comparing the energies of successive samples of each frame with a determined optimum threshold and sorting samples which have a high probability of belonging to a 'noise only' class into this class, and then for each of these samples detecting those that have a sufficiently high energy so that they have a high probability of belonging to a 'noise+useful signal' class, this second class being defined using the first class as a reference.
