中文摘要：
这研究调查一个新奇方法数字地产生塑造脉搏基于的直角的 ultrawide 乐队(UWB ) 压缩啁啾信号。首先，有不到 1 ns 持续时间时间的一个脉搏模板，被用来构造一个 Hermitian 矩阵，被生产与一压缩啁啾脉搏。亚毫微秒直角的脉搏然后被使用 Hermitian 矩阵特徵向量为 UWB 产生。模拟结果证明力量光谱塑造脉搏的 UWB 的密度分发遇见了联邦通讯委员会(FCC ) 的限制光谱面具。塑造的脉搏不仅有更高的光谱利用比率和很短的时间持续时间而且有优秀自相关和跨关联的性质，它是一个优点减少在多用户之间的干扰。特别，生产亚毫微秒的一个方法由使用相对更长的持续时间的直角的 UWB 塑造脉搏啁啾信号被介绍。
英文摘要：
This study investigates a novel method to numerically generate orthogonal ultrawide band （UWB） shaping pulses based on compressed chirp signal. First, a pulse template with less than 1 ns duration time, which is used to construct a Hermitian matrix, is produced with a compressed chirp pulse. Sub-nanosecond orthogonal pulses are then generated for UWB by using the Hermitian matrix eigenvectors. The simulation results show that the power spectral density distribution of the UWB shaping pulses met the constraint of Federal communications commissions （FCC） spectral mask. The shaping pulses not only have higher spectrum utilization ratio and very short time duration but also have excellent autocorrelation and cross-correlation properties, which is an advantage to reduce the interference between multiusers. Especially, a method to produce sub-nanosecond orthogonal UWB shaping pulses by using a relatively longer duration chirp signal is presented.
