中文摘要：
脉冲波形的设计是超宽带（UWB）系统的关键技术之一。为了设计满足FCC辐射掩蔽及降低系统多用户干扰的超宽带波形,首先对高斯导函数的组合进行了研究,然后在高斯组合函数的基础上提出了一种利用Gram-Schmidt正交化方法产生UWB正交成形脉冲的新方法。MATLAB仿真结果表明,产生的新UWB脉冲的功率谱密度满足FCC辐射掩蔽的限制,而且是完全正交的,可将其用于多用户通信,降低多用户干扰。
英文摘要：
The pulse waveform design is one of the key technologies of Uhra-wideband （UWB） communication systems. In order to design the Ultra-wideband pulse which can satisfy the restriction of FCC emission mask and reduce interference of multi-user systems, the combination of Gaussian derivative functions has been studied first and then a new method is proposed for UWB pulse waveform design based on the combination of Gaussian derived function and using Gram-Schmidt orthogonal methods. MATLAB simulation results show that the new designed UWB pulse waveform can satisfy the restriction of FCC emission mask and it is totally orthogonal. It can be used for multi-user communication system to reduce interference of multi-user systems.
