11. A spread spectrum digital radio communication receiver comprising means for determining a propagation profile of a propagation channel between sending means and the receiver, including at least one propagation path associated with a reception energy, means for measuring data relating to an energy distribution in the propagation profile, means for choosing a predetermined maximum number of propagation paths according to a criterion for choosing, means for estimating information symbols carried by a signal originating from said sending means and received over the propagation channel, by applying to said signal a processing taking into account the paths chosen, said spread spectrum digital radio communication receiver furthermore comprising means for selecting said criterion for choosing from several criteria, said criterion for choosing being selected as a function of the data measured by the means relating to the energy distribution in the propagation profile.
