UWB indoor positioning with UCA receiver

A uniform circular array (UCA) structure with four-element antennas is proposed to perform Angle-Of-Arrival (AOA) evaluation at the receiver in IR-UWB indoor positioning system. RSS ranging and AOA/TDOA finding based on UCA have been studied in this project. Path loss model is adopted in range estim...
