Modelling and Simulation of a Non-Coherent IR UWB Transceiver Architecture with ToA Estimation

Lately, impulse-radio (IR) based ultra wideband (UWB) has emerged as a leading candidate for short range data communications with positioning capabilities. This paper examines the performance of time of arrival (TOA) position estimation techniques of an IR UWB non-coherent energy collection receiver. We present the performance of two different algorithms, namely, the threshold-crossing (TC) and the maximum selection (MAX) algorithms in terms of time of arrival (TOA) estimation error in IEEE 802.15.3 channel models. The architectures of TOA MAX and TC algorithms, suitable for implementation into IR-UWB based non-coherent receivers are presented and evaluated in a top-down design methodology using a hardware description language. The goal is to evaluate the UWB IR energy collection receiver with TOA capabilities on a complete simulation platform
