| 摘 要： | 介绍了差分跳频技术的基本原理,分析了差分跳频技术的特点和差分跳频系统的组网技术,对差分跳频系统的误码率及在高斯白噪声条件下的多用户能力进行了理论分析,同时做出了相应的计算机仿真。仿真结果表明,系统用户数越少相应信噪比条件下的误码率越小,说明干扰越小。

| Abstract: | This paper presents a new hopping system,which is called the Differential Frequency Hopping（DFH） system.First it introduces the basic theory of the Differential Frequency Hopping（DFH） system,and studies the performance of the Differential Frequency Hopping（DFH） system and DFH networking.The performance in AWGN by using these two methods is analyzed respectively in theory,and the corresponding simulation results are given.Simulation results show that the smaller the number of the system users,a smaller error rate means a smaller interference at the corresponding SN ratio. |
