摘要
介绍了16QAM通信系统的概念、工作原理以及利用ADS软件建立通信系统模型的方法,并进行了系统分析。在ADS中,对调制信号的表示方法、脉冲形成、通道滤波、频谱分析——数值频谱和频率频谱、客户化调制等技术进行了仿真,实现了通信系统的模拟。
This paper introduces the 16QAM communication system concept, working principle, and how to use ADS software to establish the model of communication system. A system analysis is made. Such technologies in ADS are simulated as modulation signal representation, pulse shaping, channel filtering, spectrum analysis （numerical spectrum and frequency spectrum）, and customized modulation to realize the communication system simulation.
