| 摘 要： | 脉冲波形设计是关系到UWB系统性能的关键因素,基于Hermite矩阵特征向量和Chirp信号提出了一种产生UWB信号正交成形脉冲的新方法,并且得到了期望的成形脉冲.仿真结果表明,利用这种方法产生的UWB瞬时成形脉冲的功率谱密度分布符合FCC频谱规定的要求,有较高的频谱利用率,脉冲函数自相关性强,互相关为零,利于多址检测.

| Abstract: | The impulse waveform design is an important tactor that is relatect to me system performance. A new method to generate orthogonal UWB shape impulses is proposed based on the eigenvector of hermitian matrix and chirp signal, and the desired shape impulses have been given. The simulation results show that the power spectral density distribution of the short time impulses that is generated with this method is constrained to the FCC spectral mask of UWB. The UWB shape impulses given here have many characteristics such as high spectral occupation rate, high autocorrelation and zero cross-correlation. This is benefit to the multi-access detection. |
