摘要(Abstract)：
为了解决无线电应用需求与日益稀缺的频谱资源的矛盾,认知无线网络技术应运而生。根据无线网络节点工作特点,以现场可编程门阵列(FPGA)硬件电路为实验研究平台,首次对认知无线网络中双优先级MAC协议进行设计和实现。该设计充分运用FPGA的灵活性,采用硬件描述语言Verilog HDL和原理图相结合的方法,使用QuartusⅡ9.0进行电路设计。通过对电路系统统计值与理论值比较,证实该设计具有实时性好、可靠性高、可移植性强等特点,能够有效减少系统节点能耗,提高系统吞吐率,可应用于无线网络。
关键词(KeyWords)： 认知无线网络;现场可编程门阵列;双优先级MAC协议;原理图;节点能耗;吞吐率
