Abstract

According to the low cost and complexity demands in most sensor applications, a new ultra wideband (UWB) time of arrival (TOA) estimation method based on weighted energy detection is proposed in this paper. Firstly, the energy block that contains the direct path (DP) component is detected by generalized likelihood ratio test (GLRT). Then the precise position of DP within the detected energy block is obtained by channel statistics. Key parameters of performance are studied and optimized. The results compared with traditional TOA estimation algorithms also show that this method can achieve a relative high performance under low sampling rate conditions.
