耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula

SpreadSpectrum1
本人亲手做的一个matlab扩频通信系统simulink仿真系统。从发送端到接收到，每部分都相应得加了示波器或频谱仪，可以对照理论清楚观察到信号发生的变化。matlab6.5及以上版本上运行。(I personally make a matlab Spread Spectrum Communication System simulink simulation system. Send-ended to receive from every part of a corresponding increase in the oscilloscope or spectrum analyzer can be clearly observed in the control theory of signal changes. matlab6.5 and above to run.)
