M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.

这个是我个人编写的短时傅里叶变换的函数matlab.适用于语音压缩与语音分析.在其中可以加入一些自己的代码，即可改成phase vocoder(this is the STFT function which is wrote by myself(matlab). It is suit for speech compression and analyse. if you add some code in it, it can turn to a phase vocoder straightforward. )
