介绍一种基于单周期调制的载波同步超宽带(SCS—UWB)技术。首先描述该调制方式的基本调制原理与结构框架,并通过公式推导证明其理论合理性,其次对调制信号进行仿真,得到其功率谱并进行分析,最后就该调制方式的应用前景做简要介绍。
This paper proposes a SCS-UWB technique based on single-cycle modulation. Firstly the principle and framework of this modulation are illustrated, and its rationality is proved in theory. Secondly we simulate the modulated signal and analyze the power spectrum it produced. At last, the using prospect of this modulation method is briefly introduced.
