摘要
QPSK作为一种恒定包络的数字调制方式，占用射频带宽少，频带利用率高，抗干扰能力强，广泛应用于数字微波通信等系统，基于SystemView软件环境对QPSK的调制与解调进行建模、仿真，并通过眼图、信号星座图进行分析。
As a digital adjusting system with consistent amplitude, the quadrature phase shift keying（QPSK） has the advantages of smaller occupation of radio frequency , high efficiency and strong resistance to disturbance and is widely used in digital micro wave information communication system. This paper researches the simulation based on System View software, modeling the QPSR, and analyzes the system with eye chart and signal star constellation.
