LDPC(Low-density-parity-check，低密度奇偶校验)码是一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低，结构灵活，是近年信道编码领域的研究热点(LDPC (Low-density-parity-check, low-density parity check) codes are a class of sparse check matrix of linear block codes, is not only good performance approaching Shannon limit, and the decoding complexity low, flexible structure , the field of channel coding in recent years the research focus)

M-QAM constellation mapping

解决了连续马尔科夫模型训练、观测向量概率计算、输出参数估计问题，需安装HMM工具包(CHMM model,trianing and estimation)

对一个输入变化的的系统求逆，用SVM拟合逆系统(An input change system inverse fitting with SVM inverse system)

matlab在通信原理中的应用，信道编码卷积码仿真，希望大家能用得上！(matlab in Communication Theory in the application of channel coding convolutional code simulation, hope that we can useful!)

本程序是雷达SAR图像算法的经典程序集合，包含波数域算法，RD算法和CS算法，对于学习SAR成像非常有帮助(This procedure is a SAR radar image of the classic algorithm collection procedures, including the wave number domain algorithm, RD algorithm and CS algorithm for SAR imaging study very helpful)

说明：  《统计信号处理基础 估计与检测理论》，该书本书是一部经典的有关统计信号处理的权威著作。全书分为两卷，分别讲解了统计信号处理基础的估计理论和检测理论。(&quot Statistical signal processing based estimation and detection theory&quot , the book This book is a classic authority on statistical signal processing work. The book is divided into two volumes, respectively, to explain the basis of statistical signal processing, estimation theory and detection theory.)

Estimation of Tool Pose Based on Force–Density Correlation During Robotic Drilling

在一张表中标注了CTFT，DTFT，DFT之间的对应关系，列出公式，给出了简单认证，同时加上文字说明(Marked in a table of correspondence between CTFT, DTFT, DFT between lists formula gives a simple certification, plus text)
