摘要
超宽带通信是一种使用非常宽的频带来收发数据的技术,可以达到很高的数据传输速率并与别的无线传输系统互不干扰,而要实现超宽带通信,就必须要研究它的无线通信道模型。信道模型的建立是系统设计、性能优化以及深入研究的基础之一,准确、完整的模型又是建模的关键点和难点。根据目前国际上对超宽带无级通信在信道方面的研究,本文介绍了Intel,AT&T提出的两种超宽带信道模型,其中包括它们的信道测量实验环境、数据描述、路径损耗模型、多径模型等。
UltraWideband communication is the technology that employs ultraspectrum to transmit and receive data.It features highspeed data transmission and low interference with other wireless communication system.It's mainly applied to high speed wireless communication and radar communication.The architecture of an exact and complete model of its channel model is the key and difficulty as well as the basic of system design,simulation and performance optimization.It hence has become the focus of recent research both home and abroad.Based on the international research of UWBWCCM,the author in this paper introduces two models that Intel and AT&T put forward respectively,which include the channel measurement test environment,data description,path loss mode,multipath model,etc.
