摘　　要：为进一步验证数据链通信系统在复杂传输信道环境下的抗干扰性能,针对联合战术信息分发系统(JTIDS)干扰噪声的复杂和多样性问题,在分析与研究数据链通信系统基本工作原理及关键抗干扰技术的基础上,在JTIDS通信系统中,通过建立各部分结构的数学模型,运用编程语言工具对该通信系统进行模块设计、系统仿真、仿真结果分析以及抗干扰分析。系统实现了三种信道条件下的系统仿真模型设计及不同莱斯因子的误码率仿真曲线,仿真结果表明,系统抗干扰性能高,系统仿真方法和建模思想的有效性和可行性,也为进一步抗干扰提供了依据和方法。For further verification and analysis of the system of data link communications in the performance of an- ti-jamming in complex transmission channel environment, and for the complex and diversity issues of noise and inter- ference of JTIDS, the basic working principle and the key anti-jamming techniques of data link communication system are analysed, and the JTIDS communication system is designed by the tools of programming languages. The designing model and simulation of the system are given and then the simulation results are displayed, and the anti-jamming per- formance of the system is analyzed. The system is realized under three kinds of channels, which verifies the effectness and feasibility of the proposed model.
