A multifunctional 60-GHz system for automotive applications with communication and positioning abilities based on time reversal

This paper reports a multi-functional 60-GHz system which performs promising performances for short-range automotive applications such as short range RADAR with communication abilities. Experimental results validate the ability of the topology to transmit high speed data in the millimetre-wave (MMW) frequency band using Pulse Position Modulation (PPM). Using the same front-end, a positioning functionality is simultaneously assumed successfully in a Time Difference Of Arrival (TDOA) configuration. Furthermore, the Time Reversal (TR) technique is introduced and its impact on the location accuracy is presented and validated by experimental results.
