DIRTY PAPER CODING AND TOMLINSON HARASHIMA PRECODING IN mu-mimo

是对改进VRP问题，使用的是遗传算法，这是针对论文写的代码，所以很详细，并且对函数和变量都进行注释说明，当然画图是必不可少的(VRP is a problem, use of improved genetic algorithm, which is to write the code for the paper, so very detailed, and have carried on the functions and variables explanatory notes, of course, is essential to drawing)

说明：  求积分方程的离散解并比较它与真解之间的误差，用n=4的复化Simpson公式求积分方程(Seek solutions of integral equations of the discrete solution and compare it with the error between the real, the complex with n = 4 integral equation of the Formula Simpson)

小波不同于传统的傅里叶变换和短时傅里叶变换，它具有随信号频率变化的时间频率分析能力，因此可以用来去噪！(This program implement the function of the interference of the noise！)

一种新的符号定时和载波频率同步算法,该算法将OFDM符号分成几部分。它使用相关性和积累在几个OFDM同步算法对OFDM系统基于试点,使用前言快速、准确获取信号,在有限的时间建立同步,利用导频跟踪同步信息(A new symbol timing and carrier frequency synchronization algorithm is presented and the algorithm divides the OFDM symbol into several parts. It uses correlation and accumulation in several OFDM a synchronization algorithms for OFDM system based on pilot, using the preamble to fast and accurate acquire signal, establish synchronization in the limited time, and using pilot to track synchronization information)

说明：  对机械类振动信号处理，幅值谱，相位谱，自功率谱，自回归谱等(For mechanical vibration signal processing, amplitude spectrum, phase spectrum, self power spectrum, auto regression spectrum, etc.)

Implements the traditional benchmark formulation used in optimization literature

向matlab中读入s2p文件的数据。读入的数据格式为freqx[S11 S21 S12 S22](The program read .s2p file into matlab. The data matrix will have a dimension of freqx4. the four columns are [s11 s21 s12 s22].)

频域内低通滤波实现图像平滑，程序原代码来自书籍，《计算机图像处理与识别技术》，作者王耀南等(frequency low pass filter)
