摘要
针对跳频/多路频移键控(FH/MFSK)通信系统的特点和较强的抗干扰能力,研究了一种动态阻塞干扰样式——高跳速碰撞干扰,分析了高跳速碰撞干扰的基本特性和优点,建立了一种音调高跳速碰撞干扰模型,分析了对FH/MFSK系统的干扰性能,并进行了FH/MFSK系统在高跳速碰撞干扰下的误码率性能仿真。仿真结果表明,高跳速碰撞干扰对跳频体制能构成较大的威胁。
Aimming at the characteristic and preferable anti-jamming capability of frequency hopping/multiple frequency shift keying（FH/MFSK） communication system, this paper studies a dynamic blocking jamming mode： fast-hop-collision jamming, analyzes the basic characteristics and advantages of the fast-hop-collision jamming, establishes a kind of tone fast-hop-collision jamming model,analyzes the jamming performance of FH/MFSK system, and simulates the bit error ratio performance of FH/MFSK system under the fast-hop-collision jamming. The simulation result shows that the tone fast-hop-collision jamming can threaten the FH system.
