说明：  matlab绘图功能，plot，ezplot等等函数的用法及各自的特点(matlab graphics, plot, ezplot function usage, etc. and their respective characteristics)

这是一篇关于特征语音补偿方法的论文，想了解这方面知识的可以看看(This is a paper about the characteristics of speech compensation method, want to know about this aspect of knowledge can have a look)

MIMO-OFDM中基于DFT的信道估计(In MIMO-OFDM channel estimation based on DFT)

extracting the background

说明：  在matlab2019B中，已经将princomp函数改为了pca函数，功能相同，函数名改变，所以如果要使用，记得将老版本的代码中的princomp改为pca。(In MATLAB 2019b, the principal function has been changed to PCA function. The functions are the same, and the function name changes. So if you want to use it, remember to change the principal function in the old version of the code to PCA.)

It shows the results for PD vs. SNR for energy detector based on different sample numbers.
