Abstract: A method measures an angle of arrival (AOA) of an incoming signal using m separate antennas coupled via a switch with a single receiving device. The switch sequentially supplies the incoming signal to the receiver. A sampling of the incoming signal as received at the antennas has a sampling rate and cycle time performed in repetitive cycles. The receiver generates baseband signals with in-phase and quadrature components from the incoming signal and forwarding to each analog-to-digital converter to provide digitized samples. A signal processor is coupled to the respective analog-to-digital converter to analyze the digitized signals and to determine the angle of arrival of the incoming signal. The resulting phase error is compensated by sampling and signal processing. A device operates according to the method and an arrangement with a mobile transmitter and a device and software for locating the mobile transmitter by the device.
