| 摘 要： | W-CDMA系统中,各基站之间是异步时序关系.为了快速识别基站,3GPP协议引入了三步同步的小区搜索算法.第一步对主同步信道的搜索是极其重要的.采用传统的匹配滤波器结构占用的硬件资源非常庞大.主同步信道是由广义分层Golay序列构成的,根据其构造特性,我们提出一种新颖的广义分层Golay匹配滤波器(简称GHGMF).理论分析证明该结构大幅度降低了硬件实现的复杂度,对于工程应用具有重要价值.

| Abstract: | The timing relationship between base stations is asynchronous in W-CDMA system.So the three-step cell search algorithm is introduced in 3GPP protocols in order to fast identify the special base station.The first step,Primary Synchronous Channel(P-SCH) acquisition,is very important,but the conventional matched filter occupies much large hardware resources.Because the P-SCH is composed of the Generalised Hierarchical Golay(GHG) Sequence,we propose a novel GHG matched filter according to its structural property,which extremely reduces the hardware complexity.Generally speaking,such GHGMF structure is significant for engineering applications. |

| Keywords: | generalised hierarchical Golay sequence fast Golay transform matched filter non-periodic auto-correlation function |
