摘要
从FCC频谱模板出发,提出一种超宽带脉冲信号的设计方法,引入Delta算子理论使经光电导开关产生的信号能够利用连续系统设计法进行处理。该方法避免了传统数字信号处理中的系数表达精度不够及高采样率情况下的数值不稳定,适用于不同的频谱模板。在理论分析的基础上对方法进行了阐述和模拟仿真,仿真结果验证了该超宽带脉冲信号波形设计方法的有效性。
A novel design method for ultra-wideband （UWB） pulse was presented to conform to FCC spectral mask. With the introduction of delta operator theory, the high-speed sampling signal was processed like continuous signal, which could reduce the error of coefficient precision and improve the performance of UWB communication system. It is also applicable to different spectral masks. After theoretical analysis, the method was fully expatiated on and simulated. The simulation result showed the effectivity of this method.
