how to test rayleigh fading channel

MIMO（多输入多输出）信道模型建matlab环境，瑞利信道下mimo无线通信系统的仿真模及仿真(MIMO (Multiple Input Multiple Output) channel model matlab built environment, Rayleigh fading MIMO wireless communication system simulation mode and simulation)

通信类、数字基带信号的编码、解码、Simulink程序框图(Communications, digital baseband signal encoding, decoding, Simulink block diagram)

本代码用于模拟二维桁架结构在外载激励作用下、存在动力吸振器的情况下的响应情况，完全原创，只有一个m文件用于生成桁架振动动画的avi文件，其余三个函数用于辅助生成具体桁架结构的参数以及辅助计算。外载荷频率、动力吸振器固有频率可以通过改变代码中的变量来控制。(This code is used to simulate the two-dimensional truss structure as set out under the incentive, there are circumstances in response to the situation under dynamic vibration absorber, and completely original, only one file is used to generate m truss vibration animation avi files, the remaining three functions are used to assist generate specific parameters and supporting calculations truss structure. External load frequency, dynamic vibration absorber natural frequency can be controlled by changing the variables in the code.)

灰色预测模型是一种模糊预测算法，可以对信息不完全的或不知发展规律的变量进行预测(Gray prediction model is a fuzzy prediction algorithm, you can not know or incomplete information to predict the development of the law of variable)

仿真了锁相环工作到一定时间后达到锁定状态的过程，程序采用的是一阶RC低通滤波器即二阶一型环(Simulation of the PLL to work until after a certain period of time to achieve lock-state process, the procedure is used first-order RC low-pass filter that is second-order one-ring)

通过matlab代码画出的各种概率密度函数图形仅供参考(By matlab code to draw the beta probability density function graph for reference only)

实现分水岭分割，并能对分割结果进行合并，从而有效抑制了分割效果。(Watershed segmentation, and segmentation results of the merger, which effectively inhibited the segmentation results.)

仿真实现了MUSIC、Beamformer、Capon功率谱，并未实现线性预测功率谱估计（未找到方法）。由实验结果我们可以得出结论MUSIC的估计效果最好，它可以区分800、850处来波，其他角度也可区分。(Simulation of MUSIC, Beamformer, Capon power spectrum, did not realize the power spectrum estimation linear prediction (not way to find). From the experimental results, we can draw the conclusion MUSIC best estimate of the effect, it can be distinguished to wave at 800, 850, other angles can also be distinguished.)
