OFDM上下行的链路仿真，很简单，解释的也很清楚，易懂(simulink ofdm,easy)

卫星通讯DVBS2 中对编码性能测试，通过比较最后的误码率和信噪比的关系，判断结果(satellite communication)

说明：  LFM线性调频波的matlab实现方法，并附上几种常用算法。(The Matlab implementation method of LFM chirp is accompanied by several commonly used algorithms.)

数字基带传输系统的matlab仿真与分析,内含眼图,码间干扰等(Digital baseband transmission system matlab simulation and analysis, including an eye diagram, such as inter-symbol interference)

c-c算法可计算关联维数，延迟时间，嵌入维数等，对混沌分析有很大的意义(The C-C algorithm can calculate correlation dimension, delay time, embedding dimension and so on, which is of great significance for chaos analysis.)

dynamic mobile nodes

说明：  利用伪随机序列作为发送信号，经过信道，产生了频偏和相位偏移，利用数字锁相环的原理实现对信号的频率估计和相位估计，实现信号的载波同步。(The frequency offset and phase offset are generated by using pseudo-random sequence as the transmitting signal through the channel. The frequency estimation and phase estimation of the signal are realized by using the principle of digital phase-locked loop, and the carrier synchronization of the signal is realized.)
