Abstract:
The archtecture and characteristic of digital matched filter circuit used for PN code synchronization are introduced and the method of PN code serial search acquition based on DMF has been researched in AWGN channel.Furthermore the detection probability and false alarm probability are derived for different correlation time(partitive period or whole period).Finally,the results of calculation and emulation are given in order to be employed as useful theoretical bases for reserching the acquisition performance of digital matched filter.
