摘要 在超宽带系统的MAC层中,可以根据其特点进行设计选择,这是MAC层设计时要考虑的一个重要问题。一方面要看现存的MAC协议是否适用于超宽带系统,另一方面要根据超宽带的特性要求在MAC层中加入新的技术,通过适当调整来灵活控制。本文主要对超宽带的原理、实现方式进行了介绍,对现有的MAC层协议进行了适用于UWB系统特点的改进,对改进的协议进行了仿真和结果分析。 It is an important issue to choose plans according to the characteristics of UWB systems in designing the MAC layer of them. On the one hand, the present MAC protocol can be used in them; on the other hand, new MAC technologies can be adaptive for them which can be controlled neatly. In this paper, the principle and the realization of UWB systems are introduced, and a new MAC protocol adaptive for UWB systems is developed. Simulation and reasonable conclusion analysis for the new protocol are made.
