摘要
超宽带 (UWB)多址通信是继CDMA技术之后迅速发展的一种宽带传输技术 .本文在介绍了各种UWB通信调制方式后 ,针对产生的UWB多址信号 ,分析了信号特征 ,结合数学模型 ,以简明方式分析了TM UWB与DSC UWB多址通信信号的功率谱密度分布 ,它是UWB通信系统设计与用户干扰分析的基础 .
Ultra wideband(UWB)signaling is an important new emergent technology for wideband multiple-access communication system. A theoretical analysis of UWB signals for various modulation methods is presented. Power spectral density for the time-hopping modulated UWB and for a direct sequence phase coded UWB approach are proposed, which can provide important insights into the design and interference performance of UWB communication system in a multiple-access environment.
