An integrated multi-scheme cell search platform for W-CDMA applications

This paper proposes a cell search platform that integrates multiple schemes used for different search modes in the W-CDMA systems. There are plenty of search schemes, including frequency offset compensation, partial symbol de-spreading, multiple timing candidates, random sampling, sample point reordering, serial and pipelined searches, involved in the platform. Their computing complexities, power consumptions, and search performances are all illustrated and compared in detail. An exemplified cell search platform, which integrates all these schemes, is demonstrated to trade off performance, complexity, and power consumption in the W-CDMA systems.
