Research Abstract |
In this study we pursued a study on indoor localization of a mobile wireless equipment. As usually only a narrow frequency band of is assigned for the communication of such a mobile device, there is an inherent limitation of the achievable localization precision when we use the narrow communication band for the localization. In this study we tried a stochastic approach instead of the common Euclidean technology for object positioning to overcome the limitation. For testing high precision signal processing we conducted the experiment using wireless ultrasound communication and achieved a 60dB equivalent SNR by filtering the signal with the phase-only filter which fulfills the first defined goal
