Long Term Evolution (LTE) receiver coding

ipv4过渡到ipv6的一些技术分析，希望对大家有用(ipv4 transition to ipv6 some of the technical analysis, hope for all of us)

this program simulates 1D electromagnetic Maxwell equations with absorbing boundary condition to prevent reflection from the boundaries of the problem space. this is by using finite difference time domain method FDTD

根据伊忠科、杨绍国（电子科技大学）发表的论文"分形插值图象放大和压缩编码"编程实现。(Branch, Shao- Guo Yang (University of Electronic Science and Technology) by the paper, "Fractal Image interpolation and compression coding Large" program.)

基于MATLAB的永磁同步电动机矢量控制系统，其速度环采用滑模变结构控制方法，其仿真效果非常完美，还有相关的学习资料。(Based on MATLAB PMSM vector control system, and the speed loop adopts variable structure control method, the simulation effect is very perfect, and related learning materials.)

extracts window coordinates from an image of a building. window pictures must be taken at a straight angle, and the picture needs to be shot at daylight.

说明：  BP神经网络的仿真，能够拟合各种函数，支持梯度下降法和LM两种训练算法。所有代码自己编写，没有使用matlab自带的函数，是学习的最佳范本。(The simulation of BP neural network can fit various functions and supports two training algorithms, gradient descent method and LM. All the code is written by myself, without using the functions that come with matlab, it is the best model for learning.)

Adaptive Filters 10

说明：  在机器学习问题中，很多的算法归根到底就是在求解一个优化问题，然而我们的现实生活中也存在着很多的优化问题，例如道路上最优路径的选择，商品买卖中的最大利润的获取这些都是最优化的典型例子，前面也陆续地有一些具体的最优化的算法，如基本的梯度下降法，牛顿法以及启发式的优化算法(PSO,ABC等)。(In machine learning problems, many algorithms are in the final analysis to solve an optimization problem. However, in our real life, there are also many optimization problems, such as the choice of the optimal path on the road, the acquisition of the maximum profit in the sale of goods. These are typical examples of optimization. There are also some specific optimization algorithms, such as basic gradient Descent method, Newton method and heuristic optimization algorithm (PSO, ABC, etc.).)
