Patent ID: 8054915

Claim:
A method for adjusting a pulse detection threshold in a pulse detection device or in a pulse radio ultra wideband receiver, a pulse being detected when one of the edges of the envelope of said pulse crosses said threshold, which said method consists at least in: allocating said threshold an initial value; adjusting said threshold, by variation of the value of said threshold, so long as the number of pulses detected over at least one observation window in a symbol time does not satisfy a predetermined criterion depending on a number of pulses detectable per symbol time, said adjustment being performed by iteration: in a first direction corresponding to either an incrementation or a decrementation of the threshold, until the value of said threshold has attained a first bound; in a second direction corresponding to either an incrementation or a decrementation of the threshold, said second direction being different from the first direction, if the value of said threshold has attained said first bound.
