Patent ID: 8576904

Claim:
A method of processing a pulse train of a signal modulated by a modulation based upon a discrete random time parameter, the method comprising: performing a first processing on the signal to produce a sampled signal; performing a second processing on the sampled signal by performing at least one correlation processing with a correlation mask to produce correlation values, the correlation mask corresponding to a shape of part of a sampled pulse, thresholding the correlation values with a threshold value to produce second information item corresponding to the threshold correlation values, and with two consecutive packets of second information items in each successive block of second information items being shifted by K second information items, with K being an integer and being based upon a ratio between a sampling period and a base duration; and performing a third processing to detect pulses following a first pulse by taking account of a position of the first pulse, on packets of the second information items, the packets being separated by a duration related to the discrete random time parameter, and with the third processing producing, for each successive block of N second information items, with N being an integer and with N/K binary information items respectively representing N/K possible positions of the pulses, a logic value of a binary cue defining a presence or absence of a pulse at a possible position.
