modbus通信协议的CSHARP说明，，对使用该通信协议的开发人员来说很有用途。 (modbus communication protocol CSHARP instructions, a useful tool for developers using the communication protocol.)

说明：  3. 瑞利信道中的调制解调、信道估计： (1) 请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。 (2) 在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink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。(3. Modulation demodulation and channel estimation in Rayleigh channel: (1) deduce the theoretical bit error rate performance of BPSK coherent demodulation in single-path Rayleigh channel, and draw the relationship curve between bit signal-to-noise ratio and bit error rate. (2) in single-path Rayleigh channel, please design a time-division guidance assisted channel estimation method, Simulink simulation, measure the bit error rate performance of BPSK, draw the relationship curve between bit SNR and bit error rate, and compare with the theoretical bit error rate curve.)

说明：  LED样例代码，原厂提供。凑够20个字才行吗？(Led sample code, provided by the original factory. Can you make up 20 words?)

说明：  很久很久之前，收藏的一份 清华大学 p2p相关的研究文献，希望对有需要的人有帮助，非常难得(Long, long ago, a collection of P2P-related research literature collected by Tsinghua University, hoping to help people in need, is very rare.)

说明：  中兴h608b备份文件，usb口恢复超级管理员帐号(ZTE h608b backup file, usb super-administrator account to restore the mouth)

说明：  《全面详解LTE》一书配套代码，代码完整，但是可能存在殷matlab版本问题而无法运行的情况(Complete Code for "Comprehensive and Detailed Explanation of LTE")

实现了bpsk中利用巴克码进行同步的功能。程序简单易懂，有注释。(This code use barker code in BPSK to accomplish the synchronization.)

说明：  MSK信号的调制与解调，根据书上的代码进行了修改，非常详细(Modulation and demodulation of MSK signal)
