在 Matlab 中的认知无线电系统的仿真(237512)

基带数字传输系统的仿真 基带传输系统的基本结构带限信道的仿真以及性能分析；眼图和星座图判断信号的传输质量。 (Base-band digital transmission system simulation-based transmission system with the basic structure of band-limited channel simulation and performance analysis eye diagrams and constellation to determine the signal transmission quality.)

说明：  经典无线链路预算模型，预测了在自由空间中由地形的非规则性造成的中值传输衰落。该模型适用于频段为20MHz至40GHz、路径长度为1km至2000km的情况。对于给定的传输路径，该计算机程序通过频率、路径长度、极化方向、天线高度、表面绕射率、地面有效半径和地面导电常数等参数可以确定传输损耗的大小。(Classic wireless link budget model, forecasts the in free space caused by terrain of regularity in the value decline.The model is suitable for the frequency of 20 MHZ to 40 GHZ, path length of 1 km to 2000 km.For a given transmission path, this a computer program can calculate the value of the transmission loss by frequency, path length, polarization direction, antenna height, surface diffraction, effective radius of the ground and ground conductivity constant parameters and so on.)

说明：  线性调频信号的仿真，在此基础上，结合频控阵，实现了频控阵和线性调频信号的结合，将结合后的信号作为欺骗干扰信号。(Based on the simulation of LFM signal, the combination of frequency control array and LFM signal is realized, and the combined signal is regarded as deceptive jamming signal.)

电力线信道噪声模型matlab仿真，在输入端把脉冲噪声模型放入电力线OFDM通信系统，输出端用特定算法解码。(The algorithm estimates the impulsive noise in powerline communication, and subtract out an estimate of the impulsive noise in the current OFDM frame.)

visual c++ 很好的程序例子，适合网络编程初学者编程学习(visual c++ examples of good programs, programming for beginners to learn network programming)

用于can通讯的 can 总线协议iso 15765的中文翻译，虽然有些地方不大准确，但可以对照英文一起看，方便英文不大好的同学(Communication can be used can bus protocol iso 15765 Chinese translation, although in some places is not accurate, but can be controlled in conjunction with the English, to facilitate the students English is not good)

利用C++实现的一个即时通讯系统的客户端。传输层采用的是TCP协议。这是本科时候的毕业设计，最后评定为优，希望对一些朋友能有所帮助。(The use of C++ implementation of an instant messaging system client. Transport layer protocol used is TCP. This is the time of undergraduate graduation project, and finally classified as gifted, in the hope that some of my friends can be helpful.)
