时变信道中 OFDM 信号的多 FFT 检测
多FFT解调可与相干或差动相干检测可以应用。差异相干检测可能对时变信道的优点，其中相干检测患有通道
估计误差。最好是在频域中执行的差分编码，即在整个OFDM载波。在可供下载的源代码包在http://millitsa.coe.neu.edu/?q=projects，多FFT解调与差分相干检测和多个接收元件（空间分集）来实现。

基于单片机的数字钟及秒表的设计
本程序是在单片机c51的基础上实现的数字钟和秒表的功能设计。此设计可是在时钟的基础上实现调表，也可以在时钟和秒表之间实现相互换，P2.0,P2.1,P2.2用于选择不同的数码管亮；P2.4用于调表，按下进入调表模式；p2.5使所调位加1； P2.6按键调表恢复数字计数或者秒表恢复数字钟；P2.7按键进入秒表状态。

在局域网和广域网传输DNP V3.00。
Transporting DNP V3.00 over Local and Wide Area Network.
1 Overview
1.1 Purpose
DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485). In order for devices to exchange DNP messages in a local (LAN) and/or wide area network (WAN), one must either augment the protocol to support a network environment or use an existing network transport mechanism. This document takes the latter approach specifically, to define how to transport DNP traffic on the internet protocol suite.
