RANGE MEASUREMENT APPARATUS AND METHOD USING CHAOTIC UWB WIRELESS COMMUNICATION

摘要

Provided is a range measurement apparatus and method based on chaotic ultra wideband (UWB) wireless communication. The apparatus includes a chaotic signal generating/modulating unit for generating/modulating chaotic signals and outputting them to a transceiving unit; a transceiver for transceiving radio signals; a detector for detecting the radio signals in forms of voltage signals; a transformer for sampling the analog voltage signals and outputting first digital signals of a predetermined level; a comparator for comparing levels of the analog voltage signals with a threshold value and outputting second digital signals; and a range measurement unit for calculating a leading edge, which is a moment when initial data of a packet pay load arrive, by using the binary signals from transformation of the first digital signals based on the threshold and the second digital signals, and performing range measurement based on the leading edge. This research is applied to chaotic UWB wireless communication.
