An Iterative Interference Cancellation Algorithm for Opportunistic Sensing in IEEE 802.11AD Networks

In this work, we study the problem of detecting multiple targets (echoes) and estimating their parameters by using the sector level sweep of the IEEE 802.11ad communication standard in order to realize an opportunistic radar at mmWaves. We derive an adaptive detector/estimator which extracts the prospective echoes one-by-one from the received signal, after removing the interference caused by the previously detected (stronger) targets. The numerical analysis indicates that the proposed solution can achieve detection and estimation performances close to those obtained in a single-target scenario.
