1122和1123[Braden 1989a, 1989b]。RFC 1122针对链路层、网络层和运输层;RFC 1123针对应用层。这两个RFC对早期重要的RFC文档作了大量的纠正和解释。如果要查看有关协议更详细的细节内容,它们通常是一个入口点。它们列出了协议中关于“必须”、“应该”、“可以”、“不应该”或者“不能”等特性及其实现细节。-1122 and 1123 [Braden 1989a, 1989b]. RFC 1122 for the link layer, network layer and transport layer RFC 1123 for the application layer. The two pairs of significant early RFC documents RFC made a lot of correcting and explanation. If you want to view more details about the details of the agreement, which is usually an entry point. They are listed in the agreement on the " must," " should," " may," " should" or " can not" and other characteristics and implementation details.

MODBUS RTU 51与维纶触摸屏通信例程。
应用背景51和维纶触摸屏的通信。MODBUS RTU 51与维纶触摸屏通信例程。支持的功能码:位:01(读)、05(写),字:03(读)、06(写)还有与数码管显示输入的数据!注释的也比较详细。个人觉得移植性也比较好。各种的单片机上可以移植修改,关键技术51单片机与威纶通触摸屏通讯说明
本程序仅作为一个通信示例程序,实际使用需要根据需要修改。
请使用EB8000 V3.45以上软件打开触摸屏程序,程序为压缩后的触摸屏程序,请使用EB8000软件 工具——压缩/解压缩 菜单下的工具先进行解压缩;单片机使用Keil uVision3 V3.50编译
一、硬件连接
使用ATMEl 89S52单片机。
二、软件
1、通讯环境
触摸屏设置为主站,即PLC 类型 MODBUS RTU,通讯参数设为“9600,N,8,1”。
2、触摸屏程序,需要读取八个位,以及八个字,每次最少读取16个位,字可以一次读取一个也可以一次读取八个。
有0X1-0X8八个位切换开关,6X1-6X8八个字输入元件,支持的功能码:位:01(读)、05(写),字:03(读)、06(写)
当没有写操作时,屏不断的向单片机发送如下码(16进制显示):
01 01 00 00 00 10 3D C6 (位读取)
01 03 00 00 00 08 44 0C (字读取)
此时,如果不给屏发送相应返回值的话,屏就会提示“PLC no response”
3、51单片机程序思路及说明

OFDMA正交频分多址接入是宽带通信…
OFDMA, Orthogonal Frequency Division Multiple Access is a broad band communication method. Here channel estimation is more crucial. Based on the FFT size used for OFDM transmission method that many number of channel co-efficients are to be estimated and received signals are to be equalized using this co-efficients. Various methods trying to improve the performance and fastness are proposed. As part of master thesis various methods have be studied and evaluated using the WiMAX 802.16 system.
