turbo码的matlab仿真程序，仅供参考，希望对您有用(turbo codes matlab simulation program for information purposes only, hope useful to you)

MATLAB 编程技巧（尽量避免使用循环；大型矩阵的预先定维）(MATLAB programming skills (as far as possible avoid the use of the cycle large matrix of pre-set dimension))

说明：  主要对比了干扰对齐算法中，最大信干噪比算法，交替最小化算法，最小干扰泄露算法，并且通过改变天线数量，用户数量，自由度，观察三种算法性能(alignment algorithms including max-SINR,min-WIL,min-ALT)

程序部分代码介绍： evalops是传递给适应度函数的参数，opts是二进制编码的精度，termops是选择maxGenTerm结束函数时传递个maxGenTerm的参数，即遗传代数。xoverops是传递给交叉函数的参数。mutops是传递给变异函数的参数，具体含义我也没弄懂，我觉得有点怪。(Procedures introduce some code: evalops is passed to the fitness function parameters, opts is the precision of binary code, termops is to choose the end of maxGenTerm months maxGenTerm transfer function parameters, namely, genetic algebra. xoverops is passed to cross-function parameters. mutops is passed to the variogram parameters, the specific meaning he or she I do, I feel a bit strange.)

增广的最小二乘法源程序，加以改进，可以用于动力电池的电路模型参数辨识，也可以用于超级电容的系统辨识(Augmented Least Squares source code, to be improved, can be used to power batteries of the circuit model parameters identification, super-capacitor can also be used for system identification)

这里提供了两个消除趋势相的matlab程序 在故障诊断中 要对信号进行频谱分析 而在频谱分析前要消除趋势相 这样得到的频谱 能更好的反映故障 有利于进一步诊断(Here are two trends in the elimination phase of the matlab program in fault diagnosis to the signal spectrum analysis and spectrum analysis in the former to eliminate the tendency of such spectrum can be better reflected further in favor of fault diagnosis)

The MATLAB M-file plots the level crossing rate for an input signal using the lcr function.

UWB bpsk调制方式下的matlab实现过程，很实用(UWB bpsk modulation matlab under the implementation process, it is useful)

说明：  预测编码的部分函数，如需使用还需另外编写部分函数(Predictive coding part of the functions needed to prepare the part for the use of function)
