很好用的LTE的下行信道估计mse的测试matlab编程

改程序勇于特征降维。使用PCA的方法降低特征维度(Courage to change the feature dimension reduction program. Use PCA method to reduce the dimension feature)

通过RS示波器采集程序，存储到csv文件，用matlab读取并做处理,根据这段代码可以直接代入其他示波器采集到的程序，或者是采集卡采集到的程序，只要稍作修改就可以直接拿来处理。

matlab 学习仿真资料,对于学习matlab仿真的很有帮助(matlab learn and emulate material)

说明：  BP source code for matlab

说明：  TLBO算法即教学优化算法，在一些测试函数里，优化结果明显要好于PSO和DE等其他算法(teach-learn based optimization algrithom)

#include void main(){ void strchange(char *p,int k) int total(char *q) int n char a[10],*str1 str1=a printf("请输入字符串:") scanf(" s",str1) n=total(str1) strchange(str1,n) printf(" s",str1) print(" ") } int total(char*q){ int j,sum=0 for(j=0 *q j++,q++) sum=sum+1 return sum } void strchange (char*q,int k){ int i,j,r for(i=0,j=k-1 i

这是QAM信号和PSK信号的解调程序，其中包括16-QAM,32QAM,64-QAM和M进制PSK信号。(This is PSK and QAM signal demodulation process, including 16-QAM, 32QAM. 64-QAM and M-ary PSK signals.)

关于matlab矩阵操作的初级教程，对新生很有用。建议大家看看！(Matlab matrix operation on the primary curriculum for freshmen useful. Recommendations to see everyone!)

说明：  利用反函数方法,在均匀分布的基础上产出具有瑞利分布的概率分布的数据.(By inverse function method, based on the output of uniform distribution with the Rayleigh distribution the probability distribution of the data.)

有限元差分解偏微分方程的函数,能设置初值，边界值(Difference solution of partial differential equations finite element function can set the initial value, boundary value)
