Abstract
We propose a new preamble that can reduce the performance degradation because of the diminishing of operational complexity in coarse timing acquisition. The reduced-complexity acquisition algorithm uses a received preamble that has been shortened by summing its elements group-by-group. Therefore, the performance deteriorates because it loses the impulsive autocorrelation property of the preamble after summation and correlation. In this paper, we design a preamble sequence with a sliding correlator output function that shows a distinct peak at zero delay and symmetry even after summation based on a flipping and doubly spreading concept. By comparing with other preamble sequences, we prove that the proposed preamble shows better timing acquisition performance in ultra-wideband channel environment.Copyright (c) 2013 John Wiley & Sons, Ltd.
