Abstract
A millimeter-wave (mmWave) communication system for determining a location of a first device based on a known location of a second device includes a transceiver connected to a set of antennas to communicate beams of mmWaves and to perform an estimation of a channel connecting the first device and the second device and a memory to store results of the channels estimation including pairs of beam values, wherein each pair of beam values includes a beamforming angle and an energy of the beam communicated with the beamforming angle. The system also includes a processor operatively connected to the memory and configured to select from the memory multiple pairs of beam values corresponding to beamforming communication sharing the same dominant path connecting the first device and the second device, to determine a direction of the dominant path by evaluating a beamforming model for the selected pairs of beam values, and to determine the location of the first device arranged along the direction of the dominant path with respect to the location of the second device.
