Apparatus for acquisition of synchronization of PN signal using multi-channel signal in digital communication system and method therefor

摘要

The present invention relates to code synchronization acquisition apparatus and the method, synchronous acquisition device access channel code generator for generating a reverse pilot channel code, and the access information from the reverse channel code PN code in a digital communication system; Access information channel prefix generator to generate the access information included in the access channel prefix information channel from the reverse PN code; Receiving a signal generator for generating an access channel from the reverse pilot channel received signal code and access code information channel; Reverse pilot channel correlator and outputting a pilot channel correlation coefficient obtaining a correlation coefficient between the reverse pilot channel code and the access channel received signals; In consideration of the access channel prefix information, the access information channel correlator which outputs the access channel correlation coefficient is obtained a correlation coefficient between the access channel code information and the access channel received signals; Energy calculation section which outputs a code correlation energy in accordance with the pilot channel and the access channel correlation coefficient; And code correlation by finding the maximum value among the energy, characterized in that it comprises a code synchronization control to find the code synchronization, and more may hwakdeuk synchronization in a shorter period of time as a simple circuit, reducing power consumption at the time of the access channel transmission base station It can increase the channel capacity.
