Research Status and Future Development of Transform Domain Communication System

变换域通信系统(TDCS)是一种新型无线通信系统,能够根据外界电磁环境变化主动躲避干扰,可以利用基函数的类噪声性能实现射频隐身。幅度谱成型与伪随机相位生成技术是TDCS的核心技术。简要介绍了TDCS的发展历程,对TDCS的原理与关键技术进行了分析,指出TDCS在投入实际军事应用中必须克服的难题,最后结合目前军事需求以及研究进展对TDCS的未来发展进行了展望。

Transform Domain Communication System （TDCS） is a new type of wireless communication system, which can actively avoid interference according to the change of external electromagnetic environment, and achieve RF stealth by using noise-like performance of basis function. The technologies of amplitude spectrum shaping and pseudorandom phase generating are the core technologies of TDCS. In this paper, the development process of TDCS is introduced with analysis to its principle and key technologies, and the problem existed in the actual military applications is presented. Finally, an outlook is made to the future development of TDCS according to the military needs and research progresses.
