关于信息论中的数字通信系统纠错能力仿真综合的源程序代码，m文件(On information theory, error correction in digital communication system simulation capabilities integrated source code, m file)

解决了如何进行傅里叶变换时频率轴的标定等问题(A common use of Fourier transforms is to find the frequency components of a signal buried in a noisy time domain signal)

是hht中的emd分解，很好用。可以进行经典模态分解，分解出不同的IMF（固有模态函数）(the EMD of Hilbert-huang transform .it can get IMF.)

matlab环境下计算MFCC参数（mel倒谱参数），lpcc参数（线性预测倒谱）和pitch（基因）(calculate mfcc lpcc pitch )

In this simulink model , baseband 8-ary PAM detection is simulated .A half-sine pulse shaped PAM signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The 8-ary PAM signal transmitted is recovered at the detector output.
