Template Waveform Synthesize Technique for Ultra-wide band Signal in Measuring Distance

With the very larger bandwidth, the ultra-wide band (UWB) technology has good resolution when used for short-range positioning techniques and the correct detection of the received UWB signals is one of the important factors affect the accuracy of the positioning technique. In this paper, a method used to improve the detection accuracy of the received UWB signal in multi-path environment based on the synthesize sample waveform at the UWB receiver is proposed. The results obtained from the mathematic analysis and computer simulation show that with the proposed technique, the ability to detect the UWB signal is improved, the effect of inter pulse interference (IPI) is eliminated, and the accuracy in measuring the distance is enhanced.
