The Analysis of the Preamble Acquisition Performance Based on DS/CDMA System
Yuan Ji-bin · Microprocessors · 2007
The article investigates the acquisition performance of using Baker sequence as the preamble in DS/CDMA systems.An improved method of the preamble is proposed based on digital matched filter.It not only considers the effect of frequency error and data modulation,but also realizes code synchronization and frame synchronization at the same time.By deriving the detection probability and false alarm probability,through the mixed analytical and numerical simulation results,we show that the proposed scheme performs well.
