In this paper, the authors investigate an iterative Message Passing (MP) aided PseudoNoise (PN) sequence acquisition scheme employing both beneficially selected Generator Polynomials (GPs) and multiple receive antennas in the Direct Sequence-Ultra WideBand (DS-UWB) DownLink (DL). The performance of this iterative acquisition scheme is analyzed in terms of the achievable correct detection probability. Their scheme leads to an improved correct detection performance over an extended coverage area. The emerging UWB systems are capable of supporting high-rate networking in the home at a low power consumption.
