Abstract :
A performance evaluation is carried out of a differential post detection integration (DPDI) technique for code acquisition in the return link of a satellite CDMA system in the presence of Rician fading and non-ideal frequency recovery. In particular, the preamble structure of IMT-2000 SW-CDMA air radio interface is considered for evaluating the missed detection and false alarm probabilities. An analytical approach is used for a post detection integration length equal to one, whereas simulation results are provided both for validation purposes and for evaluation of more general cases. Finally, the achieved closed form expression for the false alarm probability allows the decision threshold to be computed analytically.
