宽带短波信道仿真器软件仿真与分析

Analysis and Simulation of Wideband HF propagation Channel

随着宽带短波通信技术的发展,其工作带宽已不仅仅局限于话音带宽,传统短波信道模型的12kHz不能满足仿真这类设备通信信道的需求。为了仿真宽带短波通信信道,需研制一款宽带短波信道仿真器。在硬件实现之前,提出一种基于Simulink(仿真环境构建宽带短波信道仿真系统的方法,其有效带宽可达1MHz,并用于短波信道仿真。仿真结果验证了理论分析的正确性。通过将仿真结果与实测参数进行对比,证明了仿真系统的有效性,为下一步用硬件实现奠定了坚实的基础。

With the development of wideband HF communication systems,which bandwidth exceeds voice＇s,the bandwidth of traditional HF channel model can＇t meet the simulation demand.In order to simulate the HF channel,a wideband HF channel simulator should be developed.Before that,based on Simulink,a HF channel simulation system was built and its available bandwidth reached 1MHz,which can be applied to simulate the channel for HF radio.Simulation results compared with the actual parameters to prove the effectiveness of simulation system,validate the correctness of theoretic model,and will pave the way for our hardware design in the future.
