生成PN序列（伪随机噪声序列），阶数包括2阶，3阶，4阶，5阶，6阶，7阶，8阶。并在前面补0后形成相应的2的幂次长的序列。(Generated PN sequences (pseudo-random noise sequence), including the orders of 2 order, 3 order, 4 order, 5 order, 6 order, 7 order, 8 order. And fill in front of 0 after the formation of the corresponding power of 2-long sequence.)

这是一个可以对随机信号进行加噪，并通过QPSK和8PSK解调后，并分析误码率的程序，为m文件，比较简单，纯粹是调用自带函数制作的(This is a random signal can add noise, QPSK and 8PSK demodulation through, and after the procedure error rate analysis for the m file, relatively simple, purely native function calls made)

说明：  蚁群算法程序，能很好的帮组初学者对蚁群算法的理解。希望对你有所帮助。(Ant colony algorithm program, can help set a good understanding of the ant colony algorithm for beginners. I hope for your help.)

说明：  一个简单的图像的kl变换matlab程序,这里需要自己找图像，不如经典的lina图像(a simple image kl transform Matlab procedures here need to find your own image, as the classic images Lina)

说明：  数字通信中，对面对判决环和非面对判决环的相位估计的仿真，调制方式采用QPAK调制方式。(Digital communication for non-face to face judgment ring and phase estimation of judgment ring simulation, modulation using QPAK modulation.)

4节点板单元刚度矩阵，用于计算平面板单元刚度矩阵(4-node plate element stiffness matrix is ​ ​ used to calculate the stiffness matrix flat panel unit)

We present a study of a matrix pencil method for esti- mating parameters (frequencies and damping factors) of exponentially damped and/or undamped sinusoids in noise. Comparison of this method to a polynomial method (SVD-Prony method) shows that the matrix pencil method and the polynomial method are two special cases of a matrix prediction approach but the pencil method is more efficient in computation and less restrictive about signal poles. It is found through perturbation analysis and simulation that, for signals with un- known damping factors, the pencil method is less sensitive to noise than the polynomial method. In Appendix A, a new expression of the Cra- mer-Ran bound for the exponential signals is presented.

自适应代码，根据论文写得，结果和论文一样，可供参考。(Adaptive code, according to papers written, and papers as a result, for reference.)

是matlab之语音处理与合成工具箱这本书的随书程序，很实用哦。珍藏！！！(good!!It s useful for you !!!!!)
