This paper considers the use of differentially coherent (DC) matched filter (MF) code acquisition in a direct-sequence (DS) spread-spectrum system. Simulation results in wideband jamming are presented. The performance of structure is compared to conventional noncoherent (NC) MF acquisition. The performance measure is the mean acquisition time, TMA. The results indicate that the differentially coherent method is a robust method by allowing also wideband jamming in quite severe Doppler shifts in addition to previously investigated narrowband interference and data modulation conditions
