【摘要】 ECMA-368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480 Mb/s。文章将对ECMA-368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。更多还原

【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.更多还原
