Abstract

In this paper we 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 analysed in terms of the achievable correct detection probability. Our scheme leads to an improved correct detection performance over an extended coverage area.
