摘要
根据2ASK调制和解调过程原理,采用虚拟仪器软件LabVIEW对2ASK数字通信系统进行图形化仿真,给出了仿真程序框图,并对输入序列、已调2ASK信号波形和解调输出序列等运行结果进行观察。结果表明,程序运行良好,仿真结果正确,为分析和观察通信系统以及实验教学提供了一种新方法。
In accordance with the principle of 2ASK modulation and demodulation,a graphical simulation of 2ASK Digital Communication System based on the Virtual Instrument Lab VIEW software is realized. The simulation structure of the software is introduced in detail. The simulation results of the input sequence and 2ASK signal waveform and output sequence are observed. The results show that the program performs well and the simulation results are right. It indicated a new way to analyzing and observing communication system in teaching and experiment.
