摘要
针对在信号解调实验中,商用设备封闭、实验箱设备不稳定、传统Matlab实验偏重仿真与实际脱节的不足,借鉴虚拟测试仪器仪表的工程实现方法来革新传统信号调制解调实验内容,基于软件无线电思想,设计出一套新的调制信号解调实验体系。该体系将通信原理、信号与系统和数字信号处理课程的知识点有机联系,综合在一起。同时该体系实验过程遵循工程实际,更具有现实和工程意义。
In view of the shortcomings of the closed commercial equipment, unstable laboratory box equipment and disconnection between simulation and practice in traditional Matlab experiments, a new set of modulation and demodulation signals is designed on the basis of the idea of software radio and in reference to the innovation of traditional signal modulation and demodulation experiment content by using engineering realization method of virtual test instruments. This system integrates communication principles, signal and knowledge points of system and digital signal processing courses. At the same time, the experimental process of the system follows the engineering practice, and has more practical and engineering significance.
