基于硬件平台的认知无线电频谱检测算法实现

摘要

以软件无线电平台为依托,实现了认知无线电中一种常用的频谱检测算法——能量检测算法,并编写程序发送已知信号来验证了这种算法的正确性.实验通过增强多媒体多播物理层技术方案的验证和演示,搭建该验证和演示硬件平台,完成硬件平台调试.本实验的最大特点就是使用了物理实现的方式进行算法实现,使理论结果更贴近现实并更具说服力.%In this paper, the software radio platform as the basis to achieve a common cognitive radio spectrum sensing algorithm-energy detection algorithms, and programming are known to send signals to verify the correctness of this algorithm. The study provides enhancements for the new multimedia multicast physical layer technology validation and demonstration program, set up the validation and demonstration hardware platform, complete hardware platform for debugging. In this study, the most important feature of this experiment is to use the physical implementation of the algorithm, so that theoretical results are closer to reality and more convincing.
