Abstract

A noncoherently combined (NC) I-Q matched-filter (MF) detection scheme is considered for serial direct-sequence code acquisition in a nonselective Rayleigh fading channel with a Gauss-Markov correlation model. The closed form expressions of the detection and false alarm probabilities of the NC I-Q MF detector for the considered Rayleigh channel are derived. This serial NC I-Q acquisition system is compared with the conventional parallel I-Q acquisition system by mean acquisition time performance. Numerical results show that the serial NC I-Q system significantly outperforms the parallel I-Q system
