摘要: 论文建立了短波数据链多音并行体制的通信仿真模型，在此模型的基础上分析研究了其抗窄带干扰和宽带干扰的性能。提出了一种针对窄带多音干扰的短波数据链副载波跳变抗干扰新方法，并通过建立的通信仿真模型多音副载波在信道带宽内、信道带宽外跳变等多种条件下进行了仿真。仿真结果表明，基于多音并行体制短波战术数据链通信使用该方法能够有效躲避多音等窄带干扰。Abstract: The communication simulation model of HF multitone parallel transmission is established，and the anti-jamming performance of narrowband and broadband is analyzed based on the model. A new method of subcarriers skipping anti-jamming for HF Tactical Data Links (TDLs) is presented aiming at narrowband multitone jamming, and simulations are made under the multiple conditions of skimming in or outside the channel bandwidth based on the communication simulation model. The simulation results show that the HF TDLs communication based on multitone parallel transmission can avoid narrowband jamming effectively such as multitone jamming.
