超宽带系统的脉位调制技术研究

摘要

UWB is different with other traditional wireless communication technology.Some factors are studied that affect the pulse position modulation of UWB signal.It gives a brief introduction about characters of UWB,modulation and demodulation principles and merits,and focuses on analysis of modulation and demodulation principles of non-carrier TH-PPM.Finally,by theory,in combination with matlab simulation,it is concluded that period of time-hopping code will effect modulation.%超宽带是一种与传统无线通信技术有所区别的通信,针对影响超宽带脉位调制技术的因素进行了研究,简要介绍了超宽带的技术特征、调制解调原理和技术优点,重点分析了无载波的TH-PPM信号调制与解调的原理,最后通过理论研究,结合脉位调制的matlab仿真实验,得出跳时码周期对脉位调制的影响。
