Abstract
The mean acquisition time performance of a straight, serial-search direct-sequence spread spectrum (DS-SS) acquisition system, operating in nonselective and frequency-selective Rician fading channels is analyzed. The system was proposed by Polydoros and Weber (1984), and its performance is analyzed for a nonfading channel, at which all the cells that fall under hypothesis H/sub o/ are statically identical. This is not the case for the Rician fading channel. A signal flow graph for which the H/sub o/ cells are not identical is used to derive an expression for the mean acquisition time in terms of the probabilities of detection and false alarm. These probabilities are then derived for the nonselective and frequency selective Rician fading channels. The results show the effect of the channel and system parameters on the mean acquisition time performance. >
