协作通信中的af-df转发源码，matlab版本 (Cooperative communications forward in af-df source, matlab version)

毕业设计源码！关于语音情感识别的！希望对大家有用！(Graduation source! Emotion recognition of speech! Hope to be useful!)

这是一本学习伺服控制的好书，对于想电机控制的的可以好好学学 。(This is a learning servo control of the book, you can see.)

使用MATLAB仿真ask信号，并画出眼图，使用窗函数对数据进行功率谱计算，并画图(Use the data window function power spectrum calculation, and drawing)

power system variable step

MUSIC算法是基于天线阵列协方差矩阵的特征分解类DOA估计算法，这里给出的是基于四阶累计量的MUSIC算法。(MUSIC algorithm for DOA estimation algorithm is based on the decomposition characteristics of the antenna array covariance matrix given here is based on the fourth-order cumulant MUSIC algorithm.)

说明：  图像处理之Poisson图像融合（含程序，图片）(image fusion of Poisson)

参考Matlab提供的模块建立简化的三相锁相环的仿真模型，只保留必要的步骤，如abc-dqz只计算Vq，去除频率反馈模块和自动参数调整模块等。 建立单相锁相环的计算模型  简化单相锁相环的系统结构，保留必要的PI控制器等模块  验证并讨论输入信号频率在45-65Hz变化时设计的锁相环的动静态性能  仿真并分析三相输入信号包含谐波、不平衡和直流偏移时锁相环的锁相结果(Reference Matlab provides three-phase PLL module to establish a simplified simulation model, retaining only the necessary steps, such as abc-dqz counting only Vq, remove frequency feedback module and automatic parameter adjustment module.  simulation and analysis of the three-phase input signal contains harmonics, unbalance and DC offset PLL phase-locked Results)

说明：  要：分析和研究了授权用户和认知用户共享频谱的一种算法的性能。 针对阴影效应或信道深衰落时，单用户频谱感知算法无法识别是频带未被 使用还是信道处于深衰落的情况，在频谱感知功率控制算法上进行了改进， 以克服这种算法的不足。改进后的算法能有效地控制认知用户的发射功率， 避免对授权用户产生有害的干扰。仿真结果表明改(To: analysis and research of the authorized users to share spectrum users and a cognitive performance of the algorithm. For the shadow effect or deep fading channel, the single-user spectrum sensing algorithm can not identify a band or a channel has not been used in the case of deep fading, the spectrum sensing power control algorithm has been improved on, to overcome the deficiencies of this method. The improved algorithm can effectively control the cognitive user' s transmit power, to avoid harmful interference with authorized users. Simulation results show that the change)
