Abstract :
Leading edge detection receivers are the simplest devices intended for reception of ultra-wideband pulses. However they application for time difference of arrival (TDOA) measurements can be a source of errors which values depend on the amplitudes of received pulses. The paper describes a method for reduction of these errors. It presents necessary receiver modifications and an algorithm for TDOA value correction. The method was experimentally tested with a positioning UWB receiver. The paper contains results of measurements made in indoor environment.
