Abstract

An uniform circular array (UCA) structure with four-element antennas is proposed to perform Angle-Of-Arrival (AOA) estimation at the receiver in IR-UWB indoor positioning system. A novel algorithm named Common-Rhythm Detection is proposed to estimate Time difference of arrival (TDOA). The performances of TDOA estimation algorithms have been compared based on UCA receiver. The accuracy of estimated AOA has been evaluated. UCA structure is verified to be useful to estimate AOA by simulation and measurement results.
