摘要
信号的调制特征提取是通信领域的一个十分重要的课题。随着近几年科技的发展,调制解调技术也有了突飞猛进的进展。文章介绍了信号调制与解调的基本方法,及一些重要的调制解调方法的原理及其在生活中的重要应用。在文章的最后是笔者根据以上相关理论,运用Labview编程方法实现的几组信号的调制解调。
The modulation feature extraction of signals is a very important topic in communication area. With the recent year development of science and technology,modem technique has made rapid progresses. The present paper introduces basic methods of signal modulations and demodulations,principles of important modulation and demodulation approaches,important applications in life. At the end of the present paper is it my realized several groups of signal modulations and demodulations according to the above related theory,using Lab VIEW programming approaches.
