灰色系统GM（1，n）模型的源代码，实现多因素作用下复杂系统的预测。(Gray system GM (1, n) model of the source code, under the effect of multi-factor prediction of complex systems.)

单小区单用户多天线MIMO环境下，QPSK调制进行MMSE接收处理，比对理想，非理想和一般MMSE接收的性能(Under the single-cell single-user multi-antenna MIMO environment, QPSK modulation MMSE receiving treatment, compared to the ideal, non-ideal performance and general MMSE reception)

An ideal AC power transmission is pure sinusoidal, both its voltage and its current. With the increasing production of modern industry, more and more power electronic equipments are used and cause serious current distortion because of open and close of power electronic devices. Harmonic, a measurement of distorted degree of voltage or current, reflects the deviation from sinusoidal wave.

在Matlab环境中编制了以雨流计数法为理论基础的二维载荷谱程序,用以对混合动力电动车电机驱动系统载荷时间历程进行统计处理,得到载荷幅均值雨流矩阵,进行幅均值各自分布假设检验,以及独立性和相关性检验,获得二维联合分布概率密度函数,建立混合动力电动车电机驱动系统台架试验用二维载荷谱.(Prepared in Matlab environment of the rain flow counting method with the theoretical basis of the two-dimensional load spectrum procedure for hybrid electric vehicles on the motor drive system for statistical processing time course load, get a load amplitude mean rain flow matrix, be the mean amplitude of each distribution hypothesis testing, as well as independence and correlation test to obtain a two-dimensional probability density function of the joint distribution, the establishment of a hybrid electric vehicle motor drive system with two-dimensional bench load spectrum.)

说明：  通信系统的matlab仿真实例,有源代码和仿真图在里面，可供参考(Matlab simulation example communication system, source code and simulation diagram on the inside, for reference)

The performance coefficient depends on both the pitch angle (β) and the tip speed ratio (λ). The tip speed ratio is calculated by using blade tip speed and wind speed upstream of the rotor. The relationship between performance coeffi cient (c_p), pitch angle (β) and tip speed ratio (λ) is established by the c_p- λ approximation (3) for different blade pitch angle.
