Parallel acquisition in mobile DS-CDMA systems

This paper presents the performance of a direct sequence spread spectrum acquisition scheme in a mobile terrestrial communications system. The effects of fading, multipath, power control, shadowing, multiple access interference, adjacent cell interference, and vehicle speed are examined. The acquisition scheme uses non-coherent detection and a parallel search strategy. The analysis is done for the reverse link of a mobile CDMA system. The paper derives the acquisition performance of a mobile communications system under practical assumptions, and gives realistic capacity estimates based on acquisition performance criteria
