技术文档：OFDM联合极大似然法，符号和载波频偏估计，利用循环前缀的冗余信息实现ML估计，不需额外插入导频，其频率估计用于跟踪模式，时间估计用于捕获模式。(OFDM ML estimator for time and frequency)

这是研究欧洲DVB-T标准的一套合集，主要介绍了DVB-T单频网的同步技术，以及系统设计和实现。其中对DVB-T单频网进行了详细的讲解，对研究我国的数字电视广播技术也有很好的借鉴作用。(This is the study of the European DVB-T standard a collection, mainly introduces the synchronization technology of DVB-T single frequency network, and the system design and implementation. It make a detailed explanation of DVB-T single frequency network, also have a very good reference for digital television broadcast technology research in china.)

描述了混沌的序列的优选，如何利用均方根值进行优选。(Describes the preferred sequence of chaos, how to make use of root-mean-square value optimization.)

一篇西安电子科技大学的博士论文《LTE中MIMO_OFDM系统物理层关键技术研究》，作者李文刚，关键词：多入多出 多用户 MIMO 空时编码 功率分配 波束赋形(Xidian University, a doctoral thesis " LTE physical layer system in MIMO_OFDM key technologies" , author Liwen Gang, Keywords: Multiple Input Multiple Output Multi-user MIMO space-time coding beamforming power allocation)

Blimpduino is a very low cost open source autonomous blimp. It consists of an Arduino-based blimp controller board with on-board infrared and ultrasonic sensors and an interface for an optional RC mode, a simple gondola with two vectoring (tilting) differential thrusters, and ground-based infrared beacon. It will be available as a commercial kit, complete with a mylar envelope, in late 2008.

实现串口通信 可以收发数据 可以是数字也可以是ASCII(Serial communication)

DXF轨迹图转G代码，有 直线，圆，圆弧，样条曲线，优化多段线，多段线。与下位机串口通讯！无法编译，是因为要先注册mscomm控件(DXF trajectories turn the G-code, line, circle, arc, spline curves to optimize the polyline, polyline. With lower serial communications! Not compile because the first registered mscomm controls)
