Abstract
In CDMA (code division multiple access) system the first action for exchanging information is code acquisition which is finding spreading code position. Thus the high-speed code acquisition is very important technology for successful communication. We propose parallel code acquisition system, the code acquisition time is reduced by the parallel structure. But the parallel code acquisition structure needs so many gates that are increasing the chip area and power consumption, thus we propose the parallel code acquisition hardware with small gate design. The efficient design is achieved with function sharing and structure. The designed 16 parallel code acquisition is about 32000 gates compared with 8000 gates of one parallel code acquisition
