说明：  STC单片机多机连级串口程序可实现.416路控制. 串口和485都可以使用、 一个程序可以用在26块控制板上，通过拔码开关给板子编号，每块板可以过滤分析所接收到不同的代码。进行继电器的动作，能返回数据，因使用定时器发送返回，不会阻塞或者代码错乱、可以 用在中控，物联网，等各种控制场合。修改代码后，能达到上千路的控制。(STC single-chip microcomputer multi-level serial port program can realize 416 channel control. Serial port and 485 can be used. One program can be used on 26 control boards. Each board can filter and analyze different codes received by numbering the boards with the pull-out switch. Relay operation can return data, because the timer is used to send the return, it will not block or code confusion, and can be used in central control, Internet of things, and other control occasions. After modifying the code, it can achieve thousands of control.)

此代码为MIMO-OFDM源程序，包括PSK调制与解调，空时分组编译码，信道建模等部分(This code for MIMO-OFDM source, including PSK modulation and demodulation, space-time block coding and decoding, channel modeling and other parts)

TD LTE中的多阶QMA调制解调中的过程仿真和误码率曲线，帮助全面了解LTE原理(The process simulation and BER curve of multilevel QMA modulation and demodulation in TD LTE helps to fully understand the LTE principle.)

Symotion是一种用于运动控制的实时工业总线，基于10/100M以太网物理层，应用层使用canopen及精简协议。可应用于运动控制器，电机驱动器，PLC，编码器光栅尺与其它工业现场执行器互连。symotion总线提供安全、开放、低成本及高性能应用。(Symotion is a synchronous real-time FieldBus for Motion control . Build on a 10/100M Ethernet physical layer , and Canopen or reduced protocol Layer. interconnect between motion controllers, Motor drives, I/O modules, encoder devices and other actuators. Symotion provides Safety , Open , low cost and high performance in all applications.)

Ethercat协议栈代码示例,基于C语言，已经调试通过(The example for Ethercat slave protocol)

说明：  FM（Frequency Modulation）即调频，习惯上用FM来指一般的调频广播（76-108MHz，在中国为87-108MHz、日本为76-90MHz），事实上FM也是一种调制方式，(FM (frequency modulation) refers to the general FM broadcasting (76-108mhz, 87-108mhz in China and 76-90mhz in Japan). In fact, FM is also a modulation mode,)

编译原理的学习资料，我们上课用的，没有源码传，但又想下载东西，只好传了学习资料(Compilation Principle of learning materials, we used in class, there is no source Chuan, but want to download things, but to learn from the information passed)

MPSK信号调制方式识别仿真，可产生B，4，8PSK信号加噪声进行仿真，学习信号分析的可以参考(MPSK modulation signal recognition simulation, can generate B, 4,8 PSK signal plus noise simulation, the study of signal analysis can refer to)

该程序为LTE中3GPP协议的PUSCH信道的物理资源映射程序，可进行物理层链路的资源映射部分(The program is a physical resource mapping program for the PUSCH channel of the 3GPP protocol in LTE, and the resource mapping part of the physical layer link)

适用于MATLAB画三维彩图，可用于画多参数平面图。(It can be used for drawing three-dimensional pictures and multi parametric graphs with MATLAB.)
