加性高斯白噪声 AWGN(Additive White Gaussian Noise) 是最基本的噪声与干扰模型。加性噪声：叠加在信号上的一种噪声，通常记为n(t)，而且无论有无信号，噪声n(t)都是始终存在的。因此通常称它为加性噪声或者加性干扰。

QPSk的仿真程序，包括AWGN信道和瑞利信道波形以及星座图-QPSk simulation procedures, including the AWGN channel and Rayleigh channel waveforms as well as the constellation diagram

MODBUS协议中文完整版本，以往的资料不全，这是一份完完整整的MODBUS协议的中文资料，是开发MOUBUS协议栈软件的重要参考-MODBUS protocol full version of the Chinese past, the information was incomplete, this is a full account of the MODBUS protocol of Chinese data, the development of protocol stack software MOUBUS an important reference

　保证服务质量的QoS 路由(Quality of Service Routing) 是网络中解决QoS 问题的一项关键技术. QoS 路由 的主要目标是为接入的业务选择满足服务质量要求的传输路径,同时保证整个网络资源的有效利用. 度量参数选择问 题、寻路问题和路由信息不准确问题是QoS 路由中的几个主要研究内容. 本文围绕这三个方面,介绍了QoS 路由中的 主要问题及相关的解决办法,并探讨了今后QoS 路由可能的研究方向.-To ensure the quality of service QoS routing (Quality of Service Routing) is a network address QoS issues a key technology. QoS routing the main objective is to access business options to meet the requirements of the transmission path quality of service, while ensuring that the entire network efficient use of resources. metric parameters of choice, look for road and routing information is not accurate QoS routing problem is that several major research contents. This paper focus on three aspects, introduced the main issues in QoS routing and related solution, and to explore possible future research directions QoS routing.

用于绘制高斯噪声。这些程序都用在传输信号时的噪声信道的信噪比计算

CMPP3.0协议源码下载,实现pc短信收发。-download chinamobile Cmpp3.0 protocle suite source code. it can send or receive sms on PC.

此程序实现了一种改进的ofdm下的信道估计方法，综合了以往的几种内插方法，并加以改进-This program realise a new channel estimation beneath the ofdm system combining several former intersecting method.Furthermore, certain ameliorations are also being done.

本篇文章是配合MICROCHIP公司以太网控制器ENC28J60使用的以太网协议栈，是一种TCP/IP协议的实现，可以非常方便根据系统建立自己的TCP或者UDP等连接！-This article is in line with the Ethernet controller MICROCHIP company ENC28J60 use Ethernet protocol stack is a TCP/IP protocol realize, according to the system can easily create your own, such as TCP or UDP connections!
