Abstract
A method for discriminating a noise pulse from a background noise in which a signal of interest is converted to an envelope signal using an entropy-based envelope generator, which envelope signal is then integrated over a plurality of consecutive integrative periods, producing an integrated envelope signal for each of the integration periods. The ratio of the envelope signal at the end of each of the integration periods corresponding to each corresponding said integrated envelope signal is determined and compared with a predetermined threshold signal for each of the integration periods, resulting in a comparison value. The integration period in which the comparison value exceeds the predetermined threshold signal and which is preceded by two integration periods in which the comparison value does not exceed the threshold value represents the point in time at which the noise pulse is detected.
