Abstract

In this paper, a low-complexity frequency-domain algorithm is proposed for Ultra Wideband (UWB) timing in multipath environment. By constructing the reasonable transmitted model, the algorithm can be carried out in frequency domain efficiently, inter symbol interference (ISI) and inter frame interference (IFI) are mitigated. Relative path delays and attenuations come out as by-products by one-dimensional searching. Most importantly, our timing algorithm has a very low computational requirement, which stems from simple addition and multiplication among vectors. The mean square errors (MSE) and bit error rate (BER) of this scheme are tested at the end of this paper. And comparisons demonstrate our algorithm outperforms another frequency processing method proposed in [1], [2].
