Abstract :
An improved synchronization acquisition algorithm applicable to spread-spectrum links of code division multiple access (CDMA) personal communication systems is proposed. The algorithm operates within a self-referencing matched filter synchronizer structure, and is particularly useful to reduce synchronization overhead on links designed to carry packet-type services. The proposed scheme involves a soft-decision detection algorithm which improves the acquisition performance by between 4 and 9 dB (depending on the choice of system parameters) in comparison to the one described previously by the authors (1994)
