Range-Free Localization Schemes for Large Scale

This code is related to the course Digital Communications. It easily reproduces the error probability as a function of the SNR per bit for QPSK and 16-QAM systems using MATLAB

图像处理，在WORD中写有区域生长算法的matlab代码，可直接用，也可以改进。(Image processing, written in WORD region growing algorithm matlab code, can be directly used, it can be improved.)

计算Allan方差，用于导航数据分析，对于学习allan方差有一定帮助(Allan variance calculation for navigation data analysis, learning allan variance of some help)

QPSK system simulation not working

When looking at a three-dimensional (3D) specimen through a transmitted brightfield optical microscope, only the part of the specimen contained in the focal plane appears sharp while the remainder looks smooth. The deconvolution task consists in deblurring the observed image in order to recover the original shapes of the object. Although 2D deconvolution softwares are available freely, the 3D consideration gives rise to many problems leading to the impossibility to recover the original images without any assumptions. Moreover some noise is added to the signal, it has been considered as a white Gaussian noise.

Lamb波的频散曲线，利用matlab编制了导波曲线，为导波检测模态选取提供了技术工作(Frequency dispersion curve of Lamb wave The guided wave curve is compiled by MATLAB, which provides technical work for the selection of guided wave detection mode.)

This code is useful for time series problem.

扩展的空间调制，打破了传统空间调制技术发送天线数目必须是2的幂数的限制，提高了频谱利用率。(The extented spatial modulation breaks the constraint of the traditional spatial modulation in which the number of the transmit antenna must be a power of 2 enchancing the spectrum efficiency.)

The Kalman filter is a mathematical power tool that is playing an increasingly important role in computer graphics as we include sensing of the real world in our systems. The good news is you don’t have to be a mathematical genius to understand and effectively use Kalman filters. This tutorial is designed to provide developers of graphical systems with a basic understanding of this important mathematical tool.
