一维EM算法MATLAB实现，两分支高斯混合模型，均值和方差都不相同。(one dimensino EM algorithm implemented by MATLAB. Estimate the mean and variance of Gaussian Mixture Model with two branches.)

Relaying and orthogonal frequency division multiple access (OFDMA) are the accepted technologies for emerging wireless communications standards. The activities in many wireless standardization bodies and forums, for example IEEE 802.16 j/m and LTE-Advanced, attest to this fact. The availability or lack thereof of efficient radio resource management (RRM) could make or mar the opportunities in these networks. This paper therefore provides a comprehensive RRM algorithm for OFDMA-based multi-cellular fixed relay networks in a way to ensure fairness among users with minimal impact on the network throughput (in contrast, pure opportunistic RRM techniques always favor users with good channel conditions

说明：  使用pid控制器进行控制永磁同步电机，以达到所需要的波形，进行风力控制(Using PID controller to control PMSM)

该文件是一个详细分析PID控制的文件。通过示波器，改变参数下，可以很形象的观察输出波形的变化，这样可以更加直观的学习PID控制，加深对它的理解(The file is a detailed analysis of PID control file. Through the oscilloscope, change the parameters, can be very image of the observed output waveform change, so that we can more intuitive learning PID control, deepen the understanding of it )
