摘要:

在瑞利衰落信道下,分析了跳频通信中噪声跟踪干扰的检测性能.应用认知无线电中协作频谱感知的思想,研究了AWGN(Additive White Gaussian Noise)信道下单跳信号存在干扰的检测性能,在此基础上,推导得到了瑞利衰落信道下的检测概率和虚警概率,应用硬判决中的“k out of n”准则,得到了瑞利衰落信道下噪声跟踪干扰的检测概率.仿真结果验证了理论分析的正确性.

Abstract:

Abstract: The detection performance of follower noise jamming (FNJ) for frequency hopping(FH) communication was analyzed in the Rayleigh fading channel. The detection performance of single hop was studied in the AWGN (Addive White Gaussian Noise) channel using the cooperative spectrum sensing in cognitive radio (CR). The detection probability and false alarm probability in the Rayleigh fading channel were deducted. Besides, the detection performance of FNJ in the Rayleigh fading channel was obtained using the “k out of n” rule. The simulation valified the results of theoretical analysis.

Key words: frequency hopping (FH), follower noise jamming (FNJ), Rayleigh fading channel, cooperative spectrum sensing, jamming detection
