摘要
主要针对噪声干扰中的噪声调相干扰信号进行研究,通过分析噪声调相干扰信号的性能及其对直接序列扩频通信系统的影响,建立了干扰系统和噪声调相干扰信号的仿真模型。根据仿真得出的系统影响误码率曲线,分析了不同干扰频率和不同干扰带宽下的噪声调相干扰信号对直扩系统的干扰效果,并得出了有效的结论。
A noise phase-modulation jamming signal in noise jamming is primarily studied. By analyzing the performance of noise phase- modulation jamming signal and its impact on direct sequence spread spectrum Communication system, the jamming system and noise phase- modulation jamming signal are modeled. According to the curve of BER caused by the system, the jamming effectiveness of noise phase- modulation jamming signal on direct-spread system under different jamming frequencies and jamming bandwidth is analyzed, and an approved conclusion is obtained.
