说明：  认知无线电技术的提出是为提高频谱利用率，而认知无线实现的关键技术是频谱感知，众所周知协作检测提高了衰落环境中认知用户系统检测的性能，该文章是基于协作检测提出新的检测方案，利用了双门限方法提高了系统性能，兼顾带宽有限和增强性能两个方面，是基于门限检测的协作检测性能优化的前提。对以后门限优化协作检测非常有用。(In this paper, we employ a double threshold method in energy detector to perform spectrum sensing, while a fusion center in the cognitive radio network collects the local decisions and observational values of the secondary users, and then makes the final decision to determine whether the primary user is absence or not. Simulation results will show that the spectrum sensing performance channels is improved significantly under the proposed scheme as opposed to the conventional method.)

MATLAB6.5辅助小波分析与应用.pdf,很好的小波教材(MATLAB6.5 assisted with the application of wavelet analysis. Pdf, good teaching wavelet)

该程序用来实现扩展卡尔曼滤波（EKF),仿真中用扩展卡尔曼滤波实现对雷达目标的跟踪，并估计。(The program used to implement the extended Kalman filter (EKF), simulation with extended Kalman filter to achieve the target tracking radar, and estimates.)

说明：  MATLAB用于图像或者信号压缩的程序，简单方便(MATLAB for image or signal compression procedures)

虚拟频谱分析仪。vi可以好好的学习参照设计(Virtual spectrum analyzer. vi)
