Code Detection and Acquisition Techniques in the DS/CDMA Communications
International Conference on Aerospace Sciences and Aviation Technology
In the direct sequence-code division multiple access (DS/CDMA) communications, one of the primary functions of the receiver is to despread the received PN code. This is accomplished by generating a local replica of the PN code in the receiver and then synchronizing it to the one superimposed on the received waveform. In general, this synchronization process is accomplished in two steps are; code acquisition, which is a coarse alignment process bringing the two PN sequences within one chipdoi:10.21608/asat.2009.23531 fatcat:7v3vngwbrbhvhlnujhofjowq2q
