摘要
根据蒙特卡罗仿真方法基本思想,分析了加性高斯噪声和单频干扰条件下的QPSK信号相位分布模型及其相关检测方法;讨论了加性噪声和单频干扰模型,建立了相关检测系统蒙特卡罗仿真模型,模型通过动态系统仿真软件SystemView的二次开发方法实现;进行了仿真电路设计与应用系统性能分析。
This paper analyses the model of phase distribution probability and method of coherent measuring of QPSK signal under AWAG and single sine wave interfering in accordance with basic idea of Monte Carlo method.It discusses the noise and interfering signal model, and creates model of Monte Carlo simulation of QPSK coherent measurement system. The model is realized with SystemView by its second order development method and designed to be a simulation circuit.Finally it gives an analysis of the performance of the application system.
