| 摘 要： | 在瑞利衰落信道上,在多音干扰和加性高斯白噪声共存的条件下,对采用乘积合并接收(PCR)方法的差分跳频(DFH)通信系统的误符号性能进行了理论分析.为验证理论分析的正确性,进行了相应的计算机仿真,将采用 PCR 方法的误符号性能与采用线性合并接收(LCR)方法的误符号性能作了比较.结果证实,在瑞利衰落信道上,DFH 通信系统采用乘积合并接收的方法要比采用 LCR 方法具有更好的抗多音干扰的性能. |
| 关 键 词： | 差分跳频(DFH) 多音干扰 线性合并接收 乘积合并接收(PcR) 瑞利衰落 |

| Abstract: | The symbol error rate(SER)performance of the differential frequency hopping(DFH)communication system with a product-combining receiver(PCR)was analyzed over a Rayleigh-fading channel with multi-tone jamming(MTJ)and ad- ditive white Gaussian noise(AWGN).The analysing results were validated with the simulation.The comparisons among the various receivers showed that the DFH system with PCR achieved better anti-jam(AJ)performance than that with a linear-combining receiver(LCR). |
| Keywords: | differential frequency hopping(DFH) multi-tone jamming(MTJ) linear-combining receiver(LCR) product-combining receiver(PCR) Rayleigh fading |
