电脑串口控制西门子s7-200程序，可以通过电脑直接控制PLC(Computer serial port control of Siemens S7-200 program)

psk调制,在matlab命令区输入bpskdigital[1 0 1 1 0 0 1 0],1]按运行,即可看到调制波(Psk modulation, input bpskdigital [1 0 1 0 0 0] in the matlab command area, 1] press operation, you can see the modulation wave)

作为TCP客户端跟TCP服务端进行通讯，支持modbus协议(As a TCP client to communicate with the TCP server to support the modbus protocol)

说明：  QPSK ALmouti 2x2 mimo figure

说明：  数字信号的调制识别，提取了信号的时域特征与频域特征。包含神经网络训练。(Modulation recognition of digital signal.The time-domain and frequency-domain features of the signal are extracted. Including neural network training.)

VC （MODBUS协议）上位机程序VC （MODBUS协议）上位机程序(VC （MODBUS）)

利用MATLAB/simulink实现4FSK调制(Using matlab simulink for simulation modulation 4FSk)

GMSK的调制解调原理分析，包含MATLAB程序代码，代码后有注释(GMSK modulation and demodulation principle analysis, including MATLAB program code, code after annotations.)

说明：  生成2KHz和8KHz的混合信号,使该信号通过上述滤波器,观察滤波前后的波形变化和频谱分布情况, 在改信号中加入高斯白噪声,(The mixed signal of 2KHz and 8KHz is generated so that the signal passes the above filter, the waveform change and spectrum distribution before and after filtering are observed, and Gao Si white noise is added to the modified signal.)
