Original Abstract Submitted
a communication system may include an electronic device, one or more external devices, and one or more reconfigurable intelligent surfaces (ris's). wireless signals may be incident upon the ris(s) from the external device(s). the ris(s) may have antenna elements that reflect the signals towards the electronic device while being swept over a set of reflected angles. the device may include one or more antennas that receive the reflected wireless signals. the device may perform measurements of the received wireless signals and may generate a steering vector using the measurements. the device may input the steering vector to a super-resolution algorithm that outputs angles-of-arrival of the wireless signals at the ris(s), which can be used to detect the position of the external device(s). the device may receive the wireless signals using a single antenna to minimize resource and space consumption or using multiple antennas to maximize location accuracy.
