UWB Signal Receiver Input Cancellation Efficiency in Ranging System with Onboard Speed Sensor

Abstract

Blanking and cancellation are successfully used to block the powerful interferences in many applications, but in the area of UWB navigation it is difficult to retrieve efficiency of interference cancellation. This research is devoted to the evaluation of cancellation efficiency in conditions of pulse interferences environment in an underground mine with cargos, equipped with autonomous onboard speed sensors. Using the experimentally obtained interference environment model the matched filter receiver is modelled during computer simulation. The signal-to-noise ratio on the matched filter output is increased on 1.9 dB due to the interference cancellation, making the cancellation efficiently applicable in underground mine UWB navigation
