This article presents an indoor localization system based on Impulse-Radio Ultra-Wideband.
A novel peak detection technique is proposed to be used for Round-Trip-Time ranging. Additionally, the accuracy and complexity of different positioning algorithms are studied. The effect of different configurations of the fixed and mobile transceivers on the accuracy is also analyzed. Simulations have been performed using realistic multipath channel models and the parameters of the IEEE 802.15.4a standard. These simulations show that the proposed localization system is able to achieve enough accuracy for an ambient assisted living application in any of the analyzed configurations.
