QPSK 调制全称 Quadrature Phase Shift Keying，意为正交相移键控，是 一种数字调制方式。它的频带利用率高，且抗干扰性能强，已经成为现代通信 技术中一种十分重要的调制解调方(QPSK’s full name is Quadrature Phaseshift Keying which is a kind of digital modulation types. It has been widely used in wireless communications and has become very important in modern communication because of its high bandwidth efficiency and strong anti-interference performance)

Signal processing front end for extracting the feature set is an important stage in any speech recognition system. The optimum feature set is still not yet decided. There are many types of features, which are derived differently and have good impact on the recognition rate. This paper presents one more successful technique to extract the feature set a speech signal, which can be used in speech recognition systems. Our technique based on the human auditory system characteristics and relies on the gammachirp filterbank to emulate asymmetric frequency response and level dependent frequency response.

包括语音的录制程序，加噪程序，以及标准的噪声库，还有用谱减法实现带噪语言信号的增强等程序(ncluding voice recording program, noise procedures, and standards of noise library, as well as achieve the noisy speech signal enhancement using spectral subtraction procedure)

use the k-means algorithm to cluster pixels into a number of clusters representing the texture regions.
