Abstract
The invention relates to method and device for detecting propagation paths in pulse transmission, wherein a received signal comprises pulses on each time symbol. After synchronizing a pulse-based reception, the inventive method consists (A) in determining the arrival times of pulses of the same current time symbol, (B) in generating a path hypotheses by assigning an initial score to each dated pulse, (C) in determining the arrival times of pulses of the time symbol following the current symbol, (D) in relatively comparing the arrival times of pulses of the following time symbol with the arrival times of the path hypotheses and (E) in updating scores according to the relative comparison results. Said path detecting method is suitable for pulse information transmission, in particular in UWB.
