说明：  基于matlab平台的模拟ADS-B数据的解码过程(Decoding process of simulated ADS-B data based on matlab platform)

将ADC对输入端口电压的转换结果按转换数据和对应的模拟电压的形式通过串口发送到PC机屏幕上显示(The ADC input port voltage conversion results by converting data and the corresponding analog voltage sent to the PC via the serial port on the screen)

一个用c#实现对研华ADAM4117数据采集的控件，对工控行业需要编程实现ADAM4117数据采集的开发人员有一定参考价值(A c# of Advantech ADAM4117 data acquisition control, the industrial sector need programming realize ADAM4117 data acquisition and developers have a certain reference value)

说明：  单频信号经过多径时变信道后，输出信号的包络随时间随机起伏，输出信号的频谱从冲激谱变成一个窄带频谱。径数位20，变化频率从0—2HZ随机均匀抽取。(Single-frequency signal through time-varying multipath channel, the output signal envelope random fluctuations over time, the output signal from the impulse of the spectrum into a narrow-band spectrum spectrum. Digital Drive 20, changes in frequency from 0-2HZ uniform random samples.)
