摘要
扩展频谱技术具有很强的抗干扰、抗衰落、抗多径、保密等性能，被广泛地应用于通信的各个领域。数字相关器（ＤＣＡ）专用集成电路（ＡＳＩＣ）是扩频系统中一个重要的部件。
The spread spectrum technique has the advantages of anti jamming, fade resisting, anti multipath, security, etc.So that it is widely used in the communication fields. The digial correlator (DCA) ASIC is an important device in the spread spectrum system, whose principle and composition are introduced in this paper.
