| Abstract: | 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. |
