这是一个MIMO信道容量的计算。使用SVD分解和注水定理。(This is a MIMO channel capacity calculations. Using the SVD decomposition and water-filling.)

this file give different codes of modulation

选题二、基于matlab简单图像处理系统用中值滤波方法消除噪声(Two topics, based on matlab image processing system with a simple median filter to eliminate noise)

电磁场仿真软件feko的模型文件，该文件为人体，对于仿真电磁场对于人体的影响有很大的作用。(The model file of the electromagnetic field simulation software FEKO, which is the human body, has a great effect on the human body.)

由于一般的功率放大器不是线性的，且动态范围是有限的，所以当OFDM系统内这种变化范围大的信号通过非线性部件时，信号会产生非线性失真。( As the general power amplifier is not linear, and the dynamic range is limited, so that when a large range of variation within an OFDM system, the nonlinear signal components, the signal will produce nonlinear distortion.)

将改进的粒子群算法和GA与SVM相结合，通过参数寻优构建新模型完成对空气质量指数的预测(The improved particle swarm optimization and genetic algorithm are combined with SVM. The prediction of air quality index (AQI) is completed by constructing a new model by parameter optimization.)

说明：  蚁群算法的路径规划是指再有障碍物的三维工作环境中寻找一条从起点到终点的无碰撞路径。(Path planning of ant colony algorithm is to find a collision free path from the start to the end in the three-dimensional working environment with obstacles.)

homework 3-4 is difficult

说明：  本书以MATLAB作为仿真环境，系统地介绍了滑模变结构控制的几种先进的控制方法。本书凝练了作者多年来从事控制系统教学和科研工作的经验，同时融入了国内外同行近年来取得的最新成果。(This book uses MATLAB as the simulation environment to systematically introduce several advanced control methods of sliding mode variable structure control. This book condenses the author's years of experience in teaching and scientific research on control systems, and at the same time incorporates the latest achievements made by domestic and foreign counterparts in recent years.)
