Detection and localization of multiple targets in IEEE 802.11ad networks

In this work we consider the IEEE 802.11ad communication standard operating at 60 GHz and exploit the echoes generated during the sector level sweep for target detection and localization. We propose a novel adaptive procedure that extracts the prospective echoes one-by-one from the received signal, after removing the interference caused by the previously detected (stronger) targets. The proposed detector/estimator is robust against the signal spillover and the near-far problem caused by the imperfect auto-correlation of the probing signal. Numerical examples are provided to validate the proposed solution.
