通信调制与解调模拟，matlab编写的。(communications module and demo simulate)

交织编码是一种信道改造技术，它通过信号设计将一个原来属于突发差错的有记忆信道改造为基本上是独立差错的随机无记忆信道。交织编码作为克服衰落信道中突发性干扰的有效方法，通常和其它用于纠正无记忆独立差错的信道编码相结合构成级联码，广泛应用于当代移动通信。(intertwined coding is a channel modification techniques, it will be designed to signal through an unexpected error originally belonged to the memory channel transformation is essentially independent of the random errors unmarked Recalling Channel. Coding intertwined as to overcome sudden fading channel interference effective way and the other is usually used to correct errors without memory of the independent channel coding combined constitute cascade code, Contemporary widely used mobile communications.)

说明：  用MATLAB模拟leach算法，可以实现在网络中的leach算法的功能(Leach method using MATLAB simulation can be realized in the network function of leach method)

说明：  结合DBPSK(Differential Binary Phase ShiR Keying)的LT码进行了深入的分析与仿真研究，重点讨论了LT码与调制的联 合优化问题。(The LT code combined DBPSK (Differential Binary Phase ShiR Keying) conducted in-depth analysis and simulation study focused on a the LT code modulation joint optimization problem.)

模仿南极星写的一个编码转换工具，日文，中文，uf8之间的转换。当初为了写这个工具调查了很多资料。难得的，很少人写这方面的东西。花了不少时间。(NJStar imitate write a code conversion tool, Japanese, Chinese, uf8 conversion between. We had to write this tool to investigate a lot of information. Rare, very few people write things in this regard. Spent a lot of time.)
