基于VC++的战术数据链通信仿真系统设计与实现

为了实现战术数据链通信仿真系统，在分析与研究联合战术信息分发系统（JTIDS）关键 技术的基础上，构建了战术数据链链路层仿真模型。依据仿真模型中各模块的划分，以VC+ +语言为编程实现平台，采用面向对象的程序设计方法，设计并实现了Reed-Solo mon码（RS码）编译码类、循环码移位键控类、最小移频键控类。最后在高斯白噪声信道下 对仿真系统进行了验证和性能分析。结果表明，设计的各个类模块功能满足系统指标，基于 各个类模块构建的仿真系统符合设计要求，为下一步研究JTIDS系统干扰与抗干扰性能奠定 了基础。

Design and implementation of a tactical data link communication simulation system based on VC++

Through analyzing the key technology of Joint Tactical Information Dist ribution System(JTIDS) tactical data link communication system,a simulatio n model of JTIDS system is constructed to realize the tactical data link communication simulation system. With VC++ as the programming platform, the Re ed-Solomon (RS) coding and decoding class, the Cyclic Code-Shift Keying (CCSK) class and the Minimum Frequency-Shift Keying(MSK) class are then designed and rea lized based on simulation models by using the object-oriented programming method. Finally, the simulation system is verified and its performance is analyzed in th e Additive White Gaussian Noise(AWGN) channel. The results show that functions of every designed class module can meet the specifications of the simulation system. The realized simulation system based on every class module meets the de sign requirements, which laid the foundation for further study of jamming and an ti-jamming performance of this system.
