认知无线电网络中三种频谱分配算法

MATLAB实现EMD分析振动信号时的波形匹配延拓，此方法可以一定程度上降低希尔伯特黄变换引起的端点效应(MATLAB to achieve EMD analysis of vibration signals when the waveform matching extension, this method can be reduced to some extent, the Hilbert yellow transform caused by the endpoint effect)

设备状态监测与故障诊断技术及其应用，是旋转机械的姊妹篇，对开发专家诊断系统的思路很有帮助。(Equipment condition monitoring and fault diagnosis technology and its applications, is姊妹篇rotating machinery, the experts on the development of diagnostic systems useful ideas.)

往信号里添加一个高斯白噪声，并将其显示出来(Add Gaussian white noise to the signal)

毕业设计有用，均值便宜跟踪的示例，基于互功率谱的时延估计，在matlab R2009b调试通过，多抽样率信号处理，结合PCA的尺度不变特征变换(SIFT)算法。

此程序用C语言用哈夫曼编码法实现了对英文的压缩与解压缩，是C语言编程一个比较经典的例子(this program in C language with Huffman coding method to achieve the right English compression and decompression, the C programming language is a classic example)

LMS自适应算法，对不同信道参数进行仿真，并输出计算结果(LMS adaptive algorithm, for different channel simulation parameters and output results)

在matlab中调用java的程序，简单好用，希望能帮助需要的人(using java program in matlab )

说明：  小数频锁相环建模，适用于学习了解小数频率综合器设计人群。(Modeling of fractional frequency PLL)

在一个圆柱体上用二维棉片来模拟树皮表面的粗糙效果(cylinder in a two-dimensional cotton used to simulate bark film surface roughness effects)

说明：  将三相电流实施坐标变换后得到了M-T坐标系下的电流反馈值，再经过PID调节后，形成了电流闭环控制；且定子电流通过反变换后得到静止两相坐标系的定子电压给定值，再经过SVPWM控制逆变器，得以输出三相电压(The feedback value of the current in the M-T coordinate system is obtained after the coordinate transformation of the three-phase current. After PID adjustment, the current closed-loop control is formed.The stator current is inversely transformed to obtain the stator voltage value of the static two-phase coordinate system, and then the three-phase voltage can be output by the SVPWM controlled inverter)
