2fsk调制信号在matlab里的解调实现(2fsk modulation signal demodulation in matlab to achieve)

This sourcecode extracts de melcepstrum coefficient of an audio file. You should give to de function, the audio file save as a vector, and the function returns a vector with 23 melcepstrum coefficients.

In signal processing, a window function (also known as an apodization function or tapering function[1]) is a mathematical function that is zero-valued outside of some chosen interval. For instance, a function that is constant inside the interval and zero elsewhere is called a rectangular window, which describes the shape of its graphical representation. When another function or waveform/data-sequence is multiplied by a window function, the product is also zero-valued outside the interval: all that is left is the part where they overlap, the view through the window .
