GPRS fundamental review

一个基于串口的手机短信发送/接收程序；Demo很简单，是以异步方式读写串口的；在对话框初始化中修改串口的配置参数正确后，能100％的正常发送/接收短信。 (A message based on the serial port of the mobile phone to send/receive process Demo is very simple, based on asynchronous serial reading and writing in the dialog box to initialize the serial port to modify configuration parameters correct to 100 of the normal Send/receive message.)

LDPC码不同译码算法对比。码长512，码率1/2.(LDPC code decoding algorithm comparison. Code length of 512, a rate 1/2.)

无线hart开发实现与测试,包含所有功能的说明与测试(wireless hart)

matlab仿真LDPC码，对采样点数进行PPM编码，此代码加了保护时隙(The LDPC code is simulated by matlab, and the sampling points are encoded by PPM, which adds protection time slot.)

i8320 系统服务与组件，提取自limo操作系统内核完整源代码(i8320 system services and components extracted from the limo complete source code for the operating system kernel)

说明：  在单径瑞利信道中，设计一种时分的导引辅助的信道估计方法，用Simulink和m语言进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与理论误码率曲线进行对比(In the single path Rayleigh channel, a time-division guidance aided channel estimation method is designed. The simulation is carried out with Simulink and M language. The BER performance of BPSK is measured, and the relationship curve between bit signal-to-noise ratio and BER is drawn, and compared with the theoretical BER curve)
