Abstract :
This paper deals with the timing acquisition for ultra wideband (UWB) signals in dense multipath environment. To estimate the start of the frame with respect to the receiver´s clock, least square (LS) method has recently proposed. However, that method needs accurate channel length for precise timing. In our proposed algorithm, we estimate the effective channel length by estimating the root mean square (RMS) delay spread of noisy template (NT). The results show that our proposed method has better performance than conventional correlation methods due to the improved timing acquisition.
