Abstract :
In this paper, we derive the Ziv-Zakai lower bounds for Impulse Radio (IR) Ultra-WideBand (UWB) Time Of Arrival (TOA)-based positioning and Time Difference Of Arrival (TDOA)-based positioning error based on geometry of indoor environments. We present the numerical evaluations with IEEE 802.15.4a channel model and the geometry of indoor environments of interest. As our derived bounds depend on the geometry of the indoor environments, our bounds can also be used in real environments with the channel measurements from real environments.
