| 摘 要： | 针对军事无线通信抗干扰和保密性需求，给出了自适应跳频通信系统模型。采用双态信道模型，深入分析了自适应跳频系统的抗干扰性能。分别在部分频带噪声干扰和多音干扰下，对常规跳频系统和自适应跳频系统性能进行了仿真，结果表明自适应跳频系统对上述两种干扰有较好的抗干扰性能。

| Abstract: | Considering the need of anti-jamming and secrecy in military wireless communication,model of adaptive frequency-hopping(AFH) system is given.A biconditional channel model is used.The anti-jamming capability of the AFH system is analyzed.The performances of normal frequency-hopping(FH) system and AFH system are simulated and compared under frequency noise and multi-tone interference conditions respectively.The result demonstrates that AFH system has better anti-jamming capability under the two interference conditions above. |

| Keywords: | adaptive frequency-hopping anti-jamming Gilbert-Elliot channel model |
