计算机模拟在建立新的通信系统、研究新的通信技术中起着越来越重要的作用。借助计算机模拟,人们可以方便、经济地得到某项通信新技术,甚至整个通信系统的理论数据及相关图表,作为评价的依据。通信软件的开发工作受到越来越广泛的重视。 QPSK(正交相移键控)是目前数字卫星和数字地面无线电系统经常使用的调制方式,模拟QPSK无线电信道的软件在国外已被广泛使用。本文叙述QPSK非线性无线电通信信道的模拟程序。
Computer simulation plays an increasingly important role in establishing new communication systems and studying new communication technologies. With computer simulation, people can easily and economically get a new communication technology, and even the theoretical data and related charts of the entire communication system as the basis for evaluation. The development of communications software is receiving more and more attention. QPSK (Quadrature Phase Shift Keying) is a modulation scheme frequently used in digital satellite and digital terrestrial radio systems. Software for simulating QPSK radio channels has been widely used in foreign countries. This article describes the QPSK nonlinear radio communication channel simulation program.
