In this paper we propose and investigate an iterative code acquisition scheme assisted by both search space reduction (SSR) and iterative message passing (MP), which was designed for the multiple receive antenna assisted direct sequence-ultra wideband (DS-UWB) downlink (DL). The performance of this iterative code acquisition scheme is analysed in terms of both the correct detection probability and the achievable mean acquisition time (MAT). We propose an improved criterion for designing the iterative MP based two-stage acquisition regime in terms of the achievable MAT performance. Our proposed scheme is capable of reducing the MAT by several orders of magnitude compared to the benchmark scenario, when considering the employment of long pseudonoise (PN) codes suitable for a variety of applications.
