摘要: Ultra-wideband (UWB) technology enables a high temporal resolution of the propagation channel. Consequently, channel impulse response between transmitter and receiver can be interpreted as signature for their relative positions. If position is known, indicates vice versa. This work introduces UWB geo-regioning clustering localization method based on fingerprinting, develops theoretical framework performance analysis, evaluates this approach by means results measured responses. Complexity issues are discussed dependencies signal-to-noise ratio, priori knowledge, observation window, system bandwidth investigated.
