摘    要:ECMA368标准详细说明了高速、短距无线网络的UWB(Ultra Wideband,超宽带)物理层和媒体访问控制层,它支持的频谱范围从3.1GHz至10.6GHz,支持的最大数据传输速率为480Mb/s。文章将对ECMA368第三版标准中媒体访问控制层的PCA(优先竞争访问)协议进行研究,在介绍PCA机制原理的基础上,概括PCA机制的运行过程,然后提出FPGA实现方案,并编程仿真。

关 键 词:ECMA-368  优先竞争访问  媒体访问控制  UWB

Abstract:The ECMA 368 Standard specifies the ultra wideband (UWB) physical layer (PHY) and medium access control (MAC) sublayer for a high-speed short range wireless network, utilizing all or part of the spectrum between 3100-10600MHz supporting data rates of up to 480Mb/s. The PCA protocol of MAC designed in the ECMA-368 Standard(3rd Edtion) is studied in this paper mainly. Based on the introduction to the theory of PCA, sums its process,and puts forward the FPGA realization project, administers programme and emulator.
Keywords:ECMA-368  UWB
