An indoor localization method is implemented using an indoor localization system that includes beacons in an indoor space and each periodically transmitting a localization signal, a radio badge receiving the localization signals, and a host coupled to the beacons and the radio badge. The beacons transmit the localization signals asynchronously. The indoor localization method includes a training phase and a tracking phase. During the training phase, signal vectors are formed from the localization signals received by the radio badge, and a signal ID value is generated from the signal vectors. During the tracking phase, signal vectors are formed from the localization signals received by the radio badge at a current location. An estimated position of the radio badge is obtained using the signal vectors of the tracking phase and the signal ID values.
