- 摘要：
A method for very long pseudonoise (PN) code acquisition of frequency hopping (FH) radio is presented and analyzed. This method is realized through twolevels: (1) acquisition of preamble, which consists of several short PN codes (sync prefixes) modulated by using direct sequence (DS) technique, and (2) long PN code synchronization of FH signal checking out. This scheme at the receiving side uses a set of passive correlators and a bank of active correlators. Some numerical results of acquisition performance measures in Rayleigh fading channel are presented. [Projekat Ministarstva nauke Republike Srbije, br. TR-32030]
