摘要
直接序列扩频技术以保密性强和抗多径衰落等优点而获得广泛的应用,针对在多系统兼容工作时出现的邻近通道干扰的问题,从扩频通信的工作原理入手进行分析,分析邻近通道干扰产生的来源,采用基带信号有限脉冲响应(FIR)滤波器的方式,实现邻近通道抑制的要求。在此基础上设计的解决方案,经过实际系统试验验证,可以很好地解决邻近通道干扰的问题。
Direct Sequence Spread Spectrum(DSSS) communication systems have been widely used for their unique features such as low probability-of-intercept transmission and multipath mitigation.To solve the problem of interference between adjacent channels in multi-system compatible operation,the paper,starting from the operation principle of spread spectrum communication,analyzes the source of interference between adjacent channels,and adopts a FIR filter of base band to solve the problem.Experimental results prove that the design meets the technical requirements of the project.
