ldpc_decode

LDPC码的经典的译码程序：BP译码算法(Classic LDPC code decoding procedure: BP decoding algorithm)

当M=4时，QAM的蒙特卡罗仿真程序，绘出误符号率和误码率曲线，并和理论曲线比较。(When M = 4 Shi, QAM of the Monte Carlo simulation program, draw the symbol error rate and bit error rate curve, and and the theoretical curves.)

本站以C语言和Java语言、嵌入式开发、算法实现为主，源码数量达几十万个，有200多个分类，很多都是本站会员的私家珍藏，互联网上其他地方是找不到的(The Gabor filter is basically a Gaussian (with variances sx and sy along x and y-axes respectively) modulated by a complex sinusoid (with centre frequencies U and V along x and y-axes respectively) described by the following equation)

SAVE2WORD saves plots to Microsoft Word. function SAVE2WORD(filespec,prnopt) saves the current Matlab figure window or Simulink model window to a Word file designated by filespec. If filespec is omitted, the user is prompted to enter one via UIPUTFILE. If the path is omitted from filespec, the Word file is created in the current Matlab working directory

说明：  这是一个利用GM(1,1)进行预测的matlab程序，是我在数模竞赛的时候写的，希望有用(This is a use of GM (1,1) to predict the matlab procedure is that I die in a few competitions when written in the hope that useful)

单相LCL滤波器的并网逆变器控制系统simnlink搭建图，可以一起进来学习下哦(Single-phase LCL filter and inverter control system simnlink build map, you can come together to learn next, oh)

BER of BPSK Modulation In AWGN Channel

图像隐藏和数字水印。采用在空域隐藏，在每个象素的bit位的低位藏入图片。采用在DCT系数上附加信息的方法进行。(image hiding and digital watermarking. Hidden in the airspace used in each pixel of the low bit-into the possession of photographs. Using the DCT coefficient Additional information on the methods.)
