基于System View的GSM通信系统设计与仿真研究

The Design and Simulation Study of GSM Communications System Based on System View

首先引入了GSM的系统组成及相关原理,分析了GSM接收机的原理及结构,运用System View软件仿真了一个从数字输入到数字输出的一个完整的GSM通信系统,重点设计了接收机部分及其实现功能。设计中精确地考虑某些实际效应,避免了由非线性引起的热噪声和互调乘性干扰。仿真结果验证了信号水平及调制性能。

First of all,this paper brings in GSM system composition and the related principle,and analyzes GSM receivers＇ principle and structure.It applies System View software to simulate one complete GSM communication system from digital input to digital output.It focuses on designing receivers＇ part and its realizing function.In the design it accurately considers some practical effects in order to avoid thermal noise and inter-modulation multiplicative interference due to nonlinearities.The simulation result proves signal levels and modulating performance.
