    摘要: The invention is directed to systems, methods and computer program products for determining a location of a device on a massive MIMO (multiple-input multiple-output) network. An exemplary method comprises receiving, from a device, a first signal and a second signal at a base station; measuring a first signal characteristic for the first signal and a second signal characteristic for the second signal; comparing and matching the first measured signal characteristic to a first reference signal characteristic for a first reference signal and the second measured signal characteristic to a second reference signal characteristic for a second reference signal; and determining a location of the device based on the first measured signal characteristic and the second measured signal characteristic.

    摘要: Methods and apparatus are disclosed for positioning a vehicle. An apparatus for determining positioning information for a vehicle may comprise a plurality of receive coil circuits and a hardware processor. The plurality of receive coil circuits is configured to generate voltage signals from a magnetic field. The hardware processor is configured to generate position estimates of a position of the magnetic field generator with respect to a position of the plurality of receive coils. Each of the first sequence of position estimates is determined based upon a corresponding voltage vector derived from the voltage signals and at least one of a plurality of reference vectors. The hardware processor is configured to update the plurality of reference vectors based upon the first sequence of position estimates and a second sequence of position estimates generated based upon a source different from the plurality of receive coil circuits.
