Abstract
This invention concerns a wireless data communication method, wherein a transmitter device having a first wide band antenna transmits ultra-wide band encoded 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.

Wireless data communication method between a transmitter device having a first wide band antenna for transmitting ultra wide band coded data signals, and a receiver device having a second wide band antenna for receiving direct path and/or multiple path coded data signals, the transmitted data being defined by one or more sequences of N pulses where N is an integer number higher than 1, the arrangement of N pulses of each sequence representing encoding of data relating to the transmitter device, wherein the N pulses of one pulse sequence of direct path and/or multiple path coded data signals received by the receiver device are each processed in one of N corresponding reception time windows, each of the N reception time windows being positioned in time as a function of a known theoretical arrangement of the N pulses of the signals transmitted by the transmitter device, and wherein an operation of adding the N windows is carried out in the receiver device so that the added pulse amplitude level is higher than the noise amplitude level captured by the receiver device.
