Abstract
This invention concerns a wireless data communication method, wherein a transmitter device having a first wide band antenna transmits ultra-wide band coded data signals to a receiver device having a second wide band antenna for receiving the direct and/or multiple path coded data signals. The transmitted data is defined by one or several sequences of N pulses where N is an integer number 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 direct and/or multiple path coded data signals received by the receiver device are processed each in one among N corresponding reception time windows. Each of the N reception time windows is positioned in time based on a known theoretic 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.
