This paper presents an integrated pseudo-noise (PN) code acquisition processor (CAP) for popular WCDMA, CDMA2000 and 802.11b systems. In the near future, multi-system equipment is going to be more and more popular because of its wide support of hybrid communications. The integrated processor is able to accomplish essential and high-complexity PN-code acquisitions in popular 3/sup rd/ generation WCDMA and CDMA2000 systems and IEEE 802.11b WLAN systems. Different code acquisitions in these DS-CDMA systems are generalized and carried out through a correlation-element (CE) array and some peripherals. In addition, low-power design is also involved to reduce power consumption effectively. The CAP is implemented and verified in a 1.8-V 0.18-/spl mu/m CMOS technology.
