Abstract

A UWB impulse receiver including an RF stage followed by a baseband processing stage. The baseband processing stage includes a Rake filter including a plurality of time fingers, each finger including an integrator of the baseband signal during an acquisition window, a control module, and a detection module estimating the received symbols from the integration results. During a synchronization phase, the control module drives respective positions of the acquisition windows associated with the different fingers, to scan at a reception interval, the RF stage only operating, in a course of the synchronization phase, during the plurality of acquisition windows.
