摘要
这里介绍了FSK调制信号的优缺点和实际应用情况,分析了FSK信号解调的特点,并建立了通信系统模型和各种干扰样式模型。基于相干解调情况下,分析了各种干扰样式情况下的理论误码率,通过仿真和实际测试得出了各种干扰样式对FSK信号的干扰效果。其次分析了通信信号和干扰信号的传播损耗,并计算了在不同通信距离和干扰距离时通信接收机的干信比,最终得出了最佳干扰样式下的效能。
The advantages, disadvantages and practical applications of FSK modulation signal are described, the characteristics of FSK demodulation signal discussed, and the models of communication system and various jamming forms established. Based on coherent demodulation, the theoretical error rates under various jamming forms are analyzed, and jamming effects of various jamming forms to FSK signal also obtained through simulation and test. Moreover, the transmission losses of communication signal and jamming signal are analyzed, and the JSRs on receivers in different communication ranges and jamming ranges calculated. Finally the efficiency of optimal jamming form to FSK signal is proposed.
