用谱减法实现语音的降噪，经典的谱减法完整源代码。(Of voice with spectral subtraction noise reduction, spectral subtraction classic full source code.)

经典的标量JA 模型的代码，非常适合磁滞模型初学者 我给出了两种实现方式的代码 一个用固定点迭代实现，可以容易变成c语言 另一个使用simulink 实现，可以加到控制图中作为一个子函数(the code is programmed following the classical paper of D.Jiles ,fellow of IEEE. The JA model is great and innovative work in magnetic material.)

Lte OFDM channel estimation algorithms

This control system has been successfully applied in some 750mm hot strip mill. The actual record curves indicate that the dynamic feedforward strategy can do well in controlling the tail temperature. And the FuzzyPI-Smith system can get better dynamic characteristic and effectively overcome the problems by pure lag with the traditional
