对语音信号假入宽带高斯白噪声并用小波降噪(add white noise to signal and decrease it with wavelet)

系统辨识二阶递推最小二乘算法实现。对数据进行了归一化的预处理，并且对原始数据进行一次采样(Second-order recursive least squares system identification algorithm)

说明：  使用VC与MATLAB混合编程实现了一路波形信号的FFT变换，简单修改后可以应用于信号处理程序中，由于使用了混合编程，大大减少了代码编写工作量(The use of VC and Matlab MATLAB waveform signals all the way FFT transform, simple modifications can be applied to signal processing procedures, the use of hybrid programming, greatly reducing the workload coding)

通过定义邻接矩阵，计算节点之间的最短路径长度(By defining the adjacency matrix to calculate the shortest path between node length)

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。数字信号的四相相移键控调制与解调技术以其灵活性和通用性而得到广泛的应用，符合未来数字通信技术发展的方向。随着移动通信技术的发展，以前在数字通信系统中采用FSK、ASK、PSK等调制方式，逐渐被许多优秀的调制技术所替代。(QPSK modulation partial Quadrature Phase Shift Keying, Quadrature Phase Shift Keying means, is a digital modulation. Digital signal quadrature phase shift keying modulation and demodulation technology for its flexibility and versatility which has been widely used, in line with the future direction of development of digital communication technologies. With the development of mobile communication technology, previously used in digital communication systems FSK, ASK, PSK modulation, etc., many excellent modulation gradually being replaced by technology.)
