摘　　要：为了更形象地理解和掌握跳频OFDM系统的工作过程,在分析了跳频OFDM系统原理的基础上,基于Matlab中的图形用户界面(GUI)设计了整个仿真系统,并形象地设计出结构组成图。通过对实例的仿真,从而证实了仿真系统的可行性,结果显示该仿真系统界面友好,操作简单,并可以动态地设置参数,方便了仿真过程,系统性能较好,即使在较低信噪比情况下,系统的误码率仍然较小。In order to understand working process of frequency hopping OFDM （FHOFDM） system visually, based on the analysis of the principle of FHOFDM system, the whole simulation system is designed by using graphical user interface in Matlab, and the constitutional diagram of its structure is also designed. The feasibility of the simulation system is validated by the simulation of an illustrated example. The simulated result shows that the simulation system operates easily, has friendly interface and can dynamically set parameters which facilitates the process of the simulation. The performance of the system is well and the bit error rate of the system is very small even if the signal-to-noise ratio is very low.
