瑞利信道matlab仿真源代码。简单，描述如何进行信道仿真(Rayleigh channel simulation matlab source code. Easy to describe how the channel simulation)

This is a 16 qam simulink file which can show the scatter plot. useful for students.

说明：  MUSIC算法是最经典的超分辨DOA估计方法，它利用了信号子空间和噪声子空间的正交性，构造空间谱函数，通过谱峰搜索，检测信号的DOA。MUSIC算法对DOA的估计从理论上可以有任意高的分辨率(MUSIC algorithm is the most classical super-resolution DOA estimation method. It uses the orthogonality of signal subspace and noise subspace to construct spatial spectral function, and detects the DOA of signal through peak search. MUSIC algorithm can theoretically estimate DOA with arbitrary high resolution.)

利用主成分分析和K-means聚类实现聚类的Matlab算法(principle component analysis and then use k-means clustering algorithm to realize the clustering)

its of signal and system in matlab.

用于粗糙集约简的源程序代码，里面有测试的数据介绍(The source code for rough collection, which contains test data)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated, using (7,4) cyclic code of the source-channel coding to do with a raised cosine roll-off function for base-band modulation, and then transferred to a high frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot, using the minimum Euclidean distance decoding decision, and then right channel signals, decoding, channel coding techniques used to draw and non- channel coding techniques using bit error rate plans.)

UKF code for Unscented Kalman Filter sigma calculation(UKF code)

是一个产生高斯脉冲的小程序，并且有调幅，有时延和频移，叠加了一定的高斯噪声(Is a produce gaussian pulse of small program, and have an am, time delay and frequency shift, superimposing a gaussian noise )

异步电动机数量控制完整仿真模型，可以根据实际情况写该参数，达到研究者所需要的情形(The number of complete induction motor control simulation model, the parameter can be written according to the actual situation, the researchers needed to achieve the situation)
