通过它把信号从时间域变换到频率域，进而研究信号的频谱结构和变化规律(discrete Fourier transform)

用matlab仿真来实现lms算法和NLMS算法(lms algorithm)

this programs implements the second order digital resonator.

In this file, the case of polymer casting is considered as an unsteady state heat transfer problem. The explicit scheme of finite difference approach is considered to solve the governing partial differential equation in one dimensional (radial) cylindrical coordinates.

PowerFactory入门教程，比较基础，例子丰富，很实用，入门者可以下来学习一下。(PowerFactory Getting Started Guide, the basis of comparison, examples of rich, very practical, beginners can learn about it.)

本代码是本人在做作业时所编，主要用来求解雅克比矩阵(slove jacobi matrix )

。本指南主要考虑的是代码（格式）的正确性、清晰性与通用性。本指南的 目的在于帮助写出更可能正确、易于理解、更具有共享性与更利于维护的代码。(. The main consideration in this Guide is the code (format) the accuracy, clarity and versatility. The purpose of this guide is to help write more likely to correct, easy to understand, to share more and more conducive to maintaining the code.)

STBC scheme for mimo diversity

选择一种编码方式。在这里可以采用行编码和列编码，但经过大量的实验表明，这两种编码方式的抗干扰性能不佳(choose a coding. The trip here can be used coding and coding out, but after a lot of experiments showed that both the encoding anti-jamming performance poor)

采用第二种ESPRIT算法，进行空间阵列信号频率估计(ESPRIT algorithm using the second, the spatial array signal frequency estimation)
