Digital Audio Broadcasting System Modeling and Hardware Implementation

说明：  对语音编码技术的特点进行了分析与研究, 对波形编码,声码器和混合编码三种主要 的语音编码进行了比较, 并介绍了GSM 和CD(This paper analyzes and studies the characteristics of speech coding technology, compares the three main speech codes: waveform coding, vocoder and hybrid coding, and introduces GSM and CD.)

又一个利用网上寻呼提供商的web页面来发送网上寻呼的程序，可以支持很多提供商。(Another program which uses web pages of internet call provider to send internet calling , and supports many providers)

code OFDM Matlab use in MIMO

对不同调频周期数 不同时间带宽积和不同调 频 极 性 等 多 种 组 合 情况下的 信号正交性进行了分析 发现通过不同调制参数的灵活组合可以实现 信号正交调制 (Analysis found that is orthogonal to the signal in the case of the variety of combinations of different FM number of cycles of the different time-bandwidth product and different FM polarity signal quadrature modulation can be achieved by the flexible combination of different modulation parameters)

说明：  这是最新的卫星通信基础理论的Matlab仿真实现，pcma以及信号衰减和延迟的仿真。尽管不是我本人原创，但比较都经典。文件为*.m格式 (This is the latest in satellite communications theoretical basis Matlab Simulation, pcma and signal attenuation and delay in the simulation. Although it was not my original, but more are classics. M*. document format)

用winsock实现两机通讯的一个小软件 特别简单 不再具体介绍(Winsock implementation to use two planes, a small communications software in particular is no longer easy introduction of specific)

ofdm最大似然估计 加入循环前缀 进行信道估计同步算法(ofdm Maximum Likelihood Estimation of cyclic prefix for channel estimation synchronization algorithm)

信道均衡的讲义，将均衡讲的出神入化，非常之好(Channel equalization of the handouts, will talk about the superb balance, very good)

NS中文手册，不用多说，有兴趣的朋友都知道。找了很久终于找到了，很不错，感谢作者辛苦努力和无私奉献！(NS Chinese manual, Needless to say, friends who are interested to know. Looking for a long time finally found, it is good to thank the author of hard work and selfless dedication!)
