数字通信系统QAM仿真程序，基于MATLAB。(QAM digital communication system simulation program, based on MATLAB.)

This code applies local histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The window size may be changed, however, the window shift is pixel by pixel. The output is definitely a better contrast image as compared to the input but checkerboard effect is evident.

有信道编码，调制，信道估计等，包括主成分分析、因子分析、贝叶斯分析，包括最小二乘法、SVM、神经网络、1_k近邻法。( Channel coding, modulation, channel estimation, Including principal component analysis, factor analysis, Bayesian analysis, Including the least squares method, the SVM, neural networks, 1 _k neighbor method.)

说明：  利用人工与算法、蝙蝠算法、遗传算法、粒子群算法等进行最优值的求解(Using artificial and algorithm, bat algorithm, genetic algorithm, particle swarm optimization algorithm to solve the optimal value)

this code is use do create 3d structure of 3d object

有源低通巴特沃斯滤波器设计根据给定的参数值设计有源滤波器(Active low-pass Butterworth filter design parameters according to the given active filter design)

说明：  本文针对无线网络中的多种服务类型，对 无线网络的带宽分配和接入方式进行分析，深入分析了不同类型的网络带宽资源 分配和调度算法在运行过程中对网络性能的影响。同时，本文也针对切换服务对 无线网络带宽分配的影响情况进行了分析，对切换服务的路由重建方式进行优 化，提高网络的实际运行性能。(This paper has analyzed the bandwidth allocating process of wireless network with different services types and compared the performance of different bandwidth allocating schemes. At the same time, this paper also gives an eye to the impact brought by handoff process. We have optimized the handoff rerouting process to improve the performance when the handoff process tack place. The main work and contributions are presented in the following aspects.)

GLVQ neural network, this method is suitable for the two classification results of data processing

用于计算ER随机图，可随机生成一定节点数量的无向连通图。(Randomly generate undirected graph)

利用matlab绘制等距指数坐标部分程序，参数自己修改，仅供参考。(Index of use of matlab to draw isometric coordinate part of the program, modify the parameters themselves, are for reference only.)
