一个音符起点检测程序，其中使用了非负矩阵分解以提取特征减少运算量(NOTE ONSET DETECTION USING NMF)

说明：  提取图像LBP特征，用于图像识别，能有效提高识别速度。(LBP feature extraction of image)

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.)

数字与模拟通信系统（第七版）一书中的matlab源程序(Digital and analog communication systems (seventh edition), a book of matlab source code)

说明：  蚁群算法的matlab源码,包括简单的输入，变量数，目标函数等，最后求得目标的最优解。(Ant colony matlab source code, including the simple input, the number of variables, objective function and so on, the final goal of the optimal solution obtained.)
