回顾了变换域通信系统(TDCS)的发展历程,介绍了TDCS的基本原理及关键技术,分析了其独特的抗干扰方式,并揭示了TDCS具有极强的抗干扰能力、较高频谱利用率和低截获概率/低检测概率(LPI/LPD)特性的特点。对目前TDCS投入实际应用存在的难点问题进行了分析和总结,最后展望了其良好的应用前景,为TDCS的深入研究指明了方向。
This paper reviewes the development course of Tlansfoma Domain Communication System(TDCS), introduces basic principle and key technology of TDCS, analyzes its unique anti-jamming way, and illustrates the strong anti-interference ability, high spectrum efficiency and the Low Probability of Intercept/Low Probability Detect(LPI/LPD) characteristics of TDCS. It also summarizes the research directions and open problems in TDCS area, and finally prospects the good prospect of TDCS, which points out the direction for further study of TDCS.
