中文说明： 有详细的注释，真的是一个好程序，用于信号特征提取、信号消噪，给出接收信号眼图及系统仿真误码率，STM32制作的MP3的全部资料，一个很有用的程序。
English Description：
There are detailed notes, really is a good program, used to signal feature extraction, signal denoising are receiving eye diagram of signal and system simulation of bit error rate (BER), all the information of the STM32 produced MP3, a very useful program.
