说明：  基于RSSI的定位，已知发射节点的发射信号强度, 接收节点根据接收信号的强度, 计算出传播损耗, 利用理论的或经验的信号传播模型将传播损耗转化为距离, 然后再计算出节点的位置。(Based on RSSI positioning, the transmitting signal strength of the transmitting node is known, and the receiving node calculates the propagation loss according to the received signal strength. The propagation loss is converted into distance by using the theoretical or empirical signal propagation model, and then the position of the node is calculated.)

本文所做的主要工作为：研究了JPEG2000标准的原理和基本框架，对JPEG 2000标准的核心—小波变换压缩技术进行了分析研究，概要的介绍了小波理论。对EZW算法进行了详细分析和描述，包括零树的含义、结构及其扫描方法。并应用Matlab图像处理工具箱和小波分析工具箱对图像小波变换处理，并通过接口工具Mex实现在Matlab环境下对C程序EZW编码的调用，实现了应用零树小波编码算法对图像的压缩处理，简单地实现了对JPEG 2000的仿真。(The main work that this text do is:Studied the principle and basic frames of the JPEG2000 standard, to the center of JPEG 2000- Wavelet transform compress which had been analyzed and researched .Carried on the detailed analysis and descriptions to the calculate way of EZW, include zero-tree coding, structures and it’s scans method. In Turbo C environment using C language to simulate wavelet zero-tree coding algorithm, using Matlab image processing toolbox and wavelet analysis toolbox, and using interface tool Mex to implement transferring the C program in Matlab, and implement the image compress by wavelet zero-tree transform coding methodology,and supplely implement JPEG2000.)
