摘要
针对调频和鉴频实验不能同时进行、同时展示的问题,采用NI-LabVIEW虚拟仪器与无线电收发设备NIUSRP相结合的方式,设计虚实结合的调频鉴频虚拟仿真实验平台,实现调频通信在线实验。以FM调制和FSK调制硬件实验为例,对平台进行功能测试。结果表明:该平台可以准确、高效地进行频率调制和数字调制仿真硬件实验,能够实现虚实结合、网络交互式实验教学。
In order to solve the problem that the frequency modulation and frequency discrimination experiments can′t be carried out and displayed simutaneously,a virtual simulation experiment platform of frequency modulation and frequency discrimination is designed by combining the virtual instrument of NI-LabVIEW with the radio transceiver NI-USRP,therefore the experiment of frequency modulation communication could be conducted online.Taking the hardware experiments of FM modulation and FSK modulation as examples,the design tests the function of the platform.The results show that the platform can carry out the simulation hardware experiments of frequency modulation and digital modulation accurately and efficiently,and can realize the experimental teaching in the aspects of the integration of virtuality with reality and network interaction.
