| Popis: | International audience; In the field of 60 GHz high data rate wireless communications a new method for indoor localization at 60 GHz is proposed. This method is based on the extraction of the TDOA (Time Difference of Arrival), using a MISO system. With this method, unlike conventional TDOA measurements, it is possible to perform communication and localization at the same time by transmitting two identical UWB OFDM signals using two antennas at the TX and extracting TDOA from the interference spectrum of these two signals at the RX. TDOA. In addition, The NLOS (Non line of sight) influence on the TDOA and the localization precision is investigated for different cases. This whole study is made within the framework of the WiGig alliance specifications. |
