摘要 引入Nakagami-m衰落模型,对MFSK/FFH系统在衰落信道下抗最坏部分频带干扰性能进行了研究,给出了部分频带干扰最佳干扰系数表达式和Nakagami衰落信道下MFSK/FFH误码率公式并进行了仿真验证,分析了不同衰落参数和分集数对系统性能的影响,最后仿真对比了采用自动增益控制合并(Adaptive Gain Control)与乘积合并(Product Combining)时MFSK/FFH系统的性能表现。结果表明:Nakagami衰落信道下,MFSK/FFH系统的分集接收特性能有效对抗最坏部分频带干扰,采用AGC合并算法比PC合并算法能更好的改善系统性能。 The performance of MFSK/FFH system against worst case partial band jamming over fading channel is investigated by utilizing Nakagami-m fading model.The expression of best jamming coefficient for the Partial Band Jamming and the BER expression of MFSK/FFH system over Nakagami-fading channel are derived,and their validity is verified by simulations.Subsequently,the effects of different values of fading parameter and diversity levels on system performance are analyzed.Finally,the performance of the MFSK/FFH systems with Adaptive Gain Control(AGC) combining scheme and Product Combining(PC) scheme is compared.The results show that diversity combining scheme of MFSK/FFH system can effectively confront worst case partial band jamming over Nakagami-fading channel,and the AGC scheme is better than the PC one in improving system performance.
