| 摘 要： | 同步是扩频通信中的关键问题，它一般分为同步捕获和同步跟踪两个阶段。３ＧＰＰ标准中采用了具有良好非周期相关特性的序列集，快速哈达玛变换（ＦＨＴ）等技术来实现快速同步捕获，本文对ＤＳ／ＷＣＤＭＡ中小区同步捕获的原理进行了阐释并给出了具体实现方法。

| Abstract: | As a significant problem in spread spectrum system design the synchronization can be generally divided into two phases:acquisition and tracking.In order to achieve fast initial acquisition of cells,many techniques such as using sequences with a good aperiodic correlation property,fast Hadamard transformation,noncoherent integration etc.are proposed in the standards of 3GPP (3rd Generation Project Partner).This article explains the principle of the initial synchronization(acquisition) of cells in DS/WCDMA and presents a concrete method of its realization. |
