摘要
直接序列扩频通信系统因其抗干扰性强、隐蔽性好、易于实现码分多址(CDMA)、抗多径干扰、直扩通信速率高等众多优点,在个人通信网、无线局域网、第三代移动通信、卫星通信以及军事战术通信等领域得到广泛应用。本文以扩频通信理论为基础,用MATLAB工具箱中的Simulink通信仿真模块和MATLAB函数对直接序列扩频通信系统进行了仿真分析,在给定条件下运行了仿真程序,得到了预期的结果。
The direct sequence spread spectrum communication system is widely used in various areas, such as personal communication, networks, wireless local area network, the third generation mobile communications, satellite communications and military tactical communications, because of its many advantages： strong anti-interference, good for hiding, easy to implement code division multiple access （CDMA）, anti-multipath interference, and higher DSSS communication rate.Based on spread spectrum communication theory, By using Simulink, and MATLAB function, the direct sequence spread frequency communication was simulated, and under the given conditions, the simulation program running the expected results.
