METHOD AND RECEIVER DEVICE FOR WIRELESS DATA COMMUNICATION THROUGH TEMPORALLY CODED ULTRA WIDEBAND SIGNALS

The invention concerns a wireless data communication method, wherein a transmitter device (2) having a first broadband antenna (27) transmits ultra wideband coded data signals to a receiver device (3) having a second broadband antenna (37) for receiving the direct and/or multiple path coded data signals. The transmitted data are defined by one or several sequences of N pulses where N is an integer greater than 1. The arrangement of the N pulses of each sequence represents a data coding relative to the transmitter device. The N pulses of a sequence of pulses of direct and/or multiple path coded data signals received by the receiver device are processed each in one among N reception corresponding time windows. Each of the N reception time windows is positioned in time based on a known theoretical arrangement of the N pulses of signals transmitted by the transmitter device. An adding operation of the N windows is then performed in the receiver device so that the amplitude level of the constantly added pulses is higher than the amplitude level of the noise sensed by the receiver device (3).
