UWB脉冲的优化设计

Optimal Design for UWB Pulse

从最大化频谱利用率的角度提出了一种设计超宽带(UWB)脉冲的算法,此算法是通过对理想UWB脉冲进行加窗、卷积来设计UWB脉冲的.所设计的脉冲不仅时间上受限减少了多址干扰,而且在满足频谱模板的情况下提高了频谱利用率,改善了UWB通信系统的性能.另外,本算法具有通用性与灵活性,适合任意国家的频谱模板.

A new algorithm to design ultra-wideband pulse was presented to maximize the spectrum utilization efficiencies, ultra-wideband （UWB） pulse can be obtained by windowing the ideal UWB pulse and convolution. The pulse designed here not only was limited to time so as to reduce the multiple access interference but enhanced the spectrum utilization efficiency under the spectral mask constraint, which improved the transmission quality of a UWB system. Furthermore, a flexible and effective method for designing pulses satisfying arbitrary UWB frequency emission mask is provided in this algorithm.
