短波宽带波形是现代短波通信的最新研究成果,采用带宽扩展方式实现短波高速通信。短波信道存在的各种各样强干扰信号使得干扰抑制成为现代短波宽带通信急待解决关键问题之一。针对这种现象,提出了一种基于变换域选择的双门限干扰抑制方法,该算法可以有效地选择最佳变换域去抑制干扰。仿真结果表明这种干扰抑制方法能够抑制不同类型干扰信号,在干扰环境下短波宽带波形具有较好传输性能。

WBHF（ Wideband High-Frequency Waveform）is the latest research achievement of modern HF communications,and it can implement high speed transmission by extending bandwidths.Due to various strong interference existed in HF channel,interference suppression of WBHF now becomes,one of the key problems demanding prompt solution.In light of this,an interference suppression algorithm based on transform domain selection is proposed,and this algorithm can effectively select the optimal transform domain and suppress the interference signals.Simulation results show that the proposed algorithm could suppress different interference signals and WBHF enjoys good transmission performance in jamming environment.
