摘要:

超宽带(UWB)技术具有抗干扰性能强,传输速率高,通信容量大,发送功率非常小,结构简单,保密性能好等优点. 脉冲波形的设计是UWB系统的关键技术之一,针对缺少满足中国辐射掩蔽的UWB脉冲设计的问题,分析了UWB脉冲中国辐射掩蔽限制条件,选择高斯导函数脉冲作为UWB基函数,采用迭代算法,设计了满足中国辐射掩蔽的UWB脉冲,Matlab数值仿真结果表明,该组合脉冲的频谱不仅能够满足中国辐射掩蔽的要求,而且具有较好的频谱利用率,对于推进UWB在我国的应用具有现实的工程意义.

Abstract:

The ultra-wideband (UWB) technology is with strong anti-interference performance, high transfer rate, large communication capacity, small transmission power simple structure and good security performance. The pulse waveform design is one of the key technologies of UWB systems. The China radiation mask restrictions was analyzed, and the UWB pulse design method based on Gau ssian derivative function and iterative algorithm was presented for meeting with China radiation mask. The system is simulated by Matlab platform. It is shown that the spectrum of combination pulse not only meets the requirements of China radiation mask, but also has better spectral efficiency. The algorithm has practical engineering significance of promoting UWB application in China.

Key words: ultra-wideband, China radiation mask, Gaussian derivative function pulse, iterated algorithm, spectrum utilization
