MULTILEVELTest22

This is a matlab source code algorithm for noise reduction in speech processing.

恒参信道对信号的影响。包含具体例子，信号为自编。(Constant and channel the influence of the signal.)

E-Algorithm,适用于不平衡数据的分类，而不用对数据进行预处理。MATLAB(the algorithm is suited for the classification of imbalanced data)

QC-LDPC码生成矩阵编程，围长为12，无4环(The program searches for a girth 12 QC-LDPC code given size of sub-matrix, row and column weights. The configuration of sub-matrices could also be changed. The program offers flexibility in constructing girth-12 QC-LDPC codes compared to other algorithms. The program builds a Tanner graph by connecting groups of rows and columns. A connection is made if it does not form less than twelve-cycles. The program may fail to find a code given particular parameters. It also does not find the smallest codes compared to other algorithms. )

该代码的功能是对ZF检测、MMSE检测、ZF-SIC检测的误码率性能做出比较(The code' s function is to detect ZF, MMSE detection, error rate performance ZF-SIC detection to make a comparison)

Sample PLL 3rd order Code

说明：  一个对图片进行处理的小程序（MATLAB）(a small program to deal with pictures)

不同数量的收发天线配置方式对应的信道容量仿真，可以计算当发射端未知CSI时，MIMO信道在不同信噪比下的遍历容量。(A different number of receiving antenna configuration corresponding to the channel capacity of the simulation can be calculated when the transmitter is unknown CSI, MIMO channel ergodic capacity under different SNR.)

迭代算法，利用matlab编译环境实现迭代求解矩阵最大特征值和特征向量；包含雅克比迭代、高斯迭代和SOR(Iterative algorithm, using matlab compiler environment to achieve maximum iteration for solving matrix eigenvalues ​ ​ and eigenvectors contains Jacobi iteration, Gauss and SOR iteration)

主成分分析是把原来多个变量划为少数几个综合指标的一种统计分析方法。 从数学角度来看，这是一种降维处理技术。(Principal component analysis (PCA) is a statistical analysis method that divides a number of variables into a few comprehensive indexes.From a mathematical point of view, this is a kind of dimensionality reduction technology.)
