通信原理中功率谱密度的仿真，仿真了不同占空比，等概、非等概双极性矩形随机信号的归一化功率谱密度，并分析不同信号（不同占空比，等概非等概）所包含的频谱分量，有无直流分量和定时分量信息(Communication theory in the power spectral density of the simulation, the simulation of different duty cycles, such as almost, almost bipolar rectangular Non-random signal normalized power spectral density, and the analysis of different signals (different duty cycle, etc. None of the other Summary) contains the spectrum component, with or without DC component and time component information)

说明：  这是一篇关于多用户下行链路预编码的文章，主要是从一些基本的矩阵变换以及矩阵运算方面讲解一些原理，最后给出仿真实验

是一种在线序列OS-ELM算法的MATLAB程序，可参考论文A Fast and Accurate Online Sequential Learning。(matlab codes for OS-ELM(Online Sequential ELM))

nc mfsk调制，包括了bfsk,qfsk,8fsk等东西(nc mfsk modulation, including bfsk, qfsk, 8fsk and other things)

This program implements the Local Statistics enhancement, using mean and sigma of the local mask

说明：  球杆系统的模糊pid仿真程序，包含模糊推理系统和GUI界面 (Driver Fuzzy pid simulation program, including fuzzy inference system and GUI interface)

常微分方程求解过程！主要是使用matlab环境编译的！(ordinary differential equation solving process! Mainly use Matlab environment compiler!)

im doing so much huhu

说明：  这个是matlab里基于LR算法对模拟运动模糊并且加入高斯噪声进行复原的算法(This is carried out in the recovery matlab LR algorithm based simulation of motion blur and add Gaussian noise algorithm)

maylab code for msk... you can try out different modulation techniques by this concept..
