This paper presents experimental investigations and analysis of ultra-wideband localization of body-worn antennas in an indoor environment. Three-dimensional (3-D) tracking of wearable antennas placed on the upper human body is achieved using a compact and cost-effective antenna and time of arrival (TOA) localization techniques. Various features such as rms delay spread, kurtosis, and signal amplitude...
This paper presents a study of 3D localisation of compact body-worn sensors using Ultra Wideband technology. Nine different sensor locations on the upper body of the human subject are considered. 3D localisation of the body worn sensors is achieved using time of arrival and peak detection techniques. The average 3D positioning accuracy achieved is in the range of 1 to 3 cm which are comparable with...
This paper presents experimental work on Ultra Wideband indoor positioning in presence of different objects using a compact UWB antenna using time of arrival positioning techniques. Obstacles considered are wooden table, laboratory chair and a solid wooden object. Different objects affect the accuracy in positioning depending upon the shape, size, and material of the objects. Results show that the...
