Estimating Angle-of-Arrival and Time-of-Flight for Multipath Components Using WiFi Channel State Information

Channel state information (CSI) collected during WiFi packet transmissions can be used for localization of commodity WiFi devices in indoor environments with multipath propagation. To this end, the angle of arrival (AoA) and time of flight (ToF) for all dominant multipath components need to be estim...
