摘要： The present invention concerns a receiver and a method for retrieving data from Ultra wideband radio transmission signals received by a receiver and transmitted in packets containing at least a preamble known to the receiver and a payload containing data unknown to the receiver. The payload data is formed of at least one burst containing at least one pulse. The method comprises the following steps : • receiving a signal corresponding to the preamble of a packet by a receiver; • determining the energy of the received signal; • determining weighting coefficients pm from the energy of the received signal; • receiving a signal corresponding to the payload of a packet by a receiver; • determining the energy of the received signal; • calculating a threshold depending on the weighting coefficients; • applying a decision rule based on the sampled energy, weighted by said weighting coefficients pm and depending on said calculated threshold.
