说明：  推箱子游戏,这是用matlab语言编写的源程序，有意思。(Sokoban game, which is used matlab source languages, interesting.)

一篇有关TDDLTE的频率同步的文章，介绍了LTE的帧结构，及相关频率同步的方法(An article about the frequency of synchronous TDDLTE article introduces the LTE frame structure, and related method of frequency synchronization)

LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G) (LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)

FSK调制解调程序，中频是15Mhz的，一个码元采样点250个(FSK modulation and demodulation process, 15Mhz IF yes, a symbol 250 sampling points)

用simulink搭建的自抗扰控制器非线性反馈模型(The ADRC controller simulink structures nonlinear feedback model)
