基于高斯脉冲的认知超宽带无线电波形设计

Design of Gaussian Pulse-based CUWB Radio Waveforms

为提高高斯脉冲波形的频谱利用率,讨论了高斯脉冲性能参数(微分阶数和成形因子)对其频谱产生的影响,提出了基于高斯导函数脉冲产生组合波形的方法.仿真分析表明,该组合波形的频谱不仅能满足FCC规定的辐射掩蔽的要求,而且有较好的频谱利用率。

To improve the spectrum utilization rate of Gaussian pulse waveform, the influence of Gaussian pulse performance parameters （differential orders and shape factors） on its spectrum was discussed, and a novel method for generating combinative waveforms based on Gaussian derivative function was proposed. By simulation, it shows that the spectrum of combinative waveform can not only meet the spectral radiation regulation by FCC, but also has a higher spectrum utilization ratio.
