Abstract

The key concern of this paper is to study ranging and positioning algorithms based on the estimation of time of arrival (TOA) with impulse radio ultra wide band (IR-UWB) signal And the ranging and positioning models based on IR-UWB are established; the influences of different signal noise ratio (SNR) and different Gaussian derivative pulses on ranging and positioning are analyzed. Root mean squared error (RMSE) is used to scale the performance of the ranging and positioning. Performances of the ranging and positioning models are examined through simulation. With the increasing of SNR, the accuracy of ranging and positioning is higher. Furthermore, the higher order Gaussian pulse is advised to be exploited in order to improve the accuracy of range and position estimation
