Fingerprinting localization based on 60 GHz impulse radio

Recently, 60 GHz technology has become a promising alternative for indoor positioning systems because it can provide very accurate temporal and spatial information for precise time of arrival (TOA) estimation. However, non-line-of-sight (NLOS) propagation in indoor environments can significantly degrade the localization accuracy with 60 GHz signals. To reduce the effects of NLOS propagation, a fingerprinting based localization algorithm for 60 GHz impulse radio positioning is presented. Performance results are presented which show that decimeter level accuracy can be obtained in LOS as well as NLOS environments.
