GSM移动通信网络的系统仿真研究

Simulation of GSM Mobile Communication SystemAbstract:The current era,the rapid development of science and technology,communication system experience 1G,2G,3G era developed to the current 4G.GSMis currently the world's most widely used mobile phone standard,its air interfaceusing time division multiple access technology.The widespread use of the GSMstandard allows users to easily roam between mobile phone operators who sign theRoaming Agreement.GSM is the second generation of mobile communication system,because compared with the previous standard,GSM is the biggest difference betweenthe digital signaling and voice channels.In order to further improve the GSM,theGSM system to the necessary design and simulation is essential.Simulationenvironment in the simulation process plays a role in the overall control,MATLABSimulink software with a visual graphical design capabilities,deserved to become themost suitable for this topic simulation platform.The content of this topic is Simulink simulation in the whole process of GSMcommunication and research to achieve its principles.In the system modelconstruction,the whole process of signal transmission simulation,added in thetransmission process of the signal received by the interference,but also to enhance thesystem's anti-jamming capability of the encoding,modulation technology.In theSimulink design window,the modules such as source coding and decoding,channelcoding and decoding,interleaving and deinterleaving,modulation and equalizationare designed in detail,and these modules are set up and then connected into acomplete system and the whole system is running The After the simulation process iscompleted,the simulation results are analyzed to further optimize and improve GSM.Keywords:GSM network,System simulation,Simulink simulation
