摘要
针对通信实验室硬件设备不完善的情况,在研究GSM系统原理的基础上,采用SystemView通信系统设计与仿真软件,对GSM系统的信源、信道、调制/解调等模块进行了设计与仿真。该设计避开了复杂的硬件搭建,可以在不具备实验环境的条件下同样也能完成复杂的通信系统设计与仿真。通过对GSM系统的输入波形和输出波形进行仿真分析,证明了设计系统的正确性。有助于更深层次的认识实际系统的工作原理和过程。
To deal with the availability issues of lab hardware,the modules for signal source,signal path,modulation/demodu- lation using the SystemView software are designed and simulated, as the next step in studying the GSM system. This approach avoids the complicated set-up of hardwares, and is capable of accomplishing the design and simulation without the necessary lab conditions. The effectiveness is demonstrated of the design system through the simulation analysis of the input and output wave form of the GSM system. This helps us to understand more deeply the mechanism and workings of the actual system.
