直接序列扩频通信系统仿真研究

摘要

The direct sequence spread spectrum communication system has many advantages ,including strong anti-in-terference ,good for hiding ,easy to improve signal reception ,anti-multipath interference ,and increasing channel capacity .So it is widely used in various areas ,such as cellular phone ,wireless data communication ,satellite communications and military tactical communications .Based on spread spectrum communication theory ,the direct sequence spread frequency communica-tion is simulated by using Matlab function .%直接序列扩频通信系统具有抗干扰性强、隐蔽性好、易于提高信号接收质量、抗多径干扰、增加信道容量等众多优点，在蜂窝电话、无线数据通信、卫星通信以及军事战术通信等领域得到广泛应用。论文以扩频通信理论为基础，分析了伪随机序列，并用 Matlab 对直接序列扩频通信系统进行了仿真分析。
