在通信系统中,物理层作为最底层,提供能够传送原始比特数据的物理信道.通过对GSM通信系统物理层的分析,运用Matlab/Simulink设计模型,对信道编码、交织、调制等过程进行基本仿真,最终获取信号的I/Q数据、绘制出信号的功率谱.其中GSM采用分模块编写M文件实现,通过对误比特率和误块率的分析,验证了仿真的可靠性.

In a communication system, the physical layer provides a physical channel which can transmit the raw data bits as the lowest level. After the analysis of GSM physical layer of communication systems, a basic simulation about channel coding, interleaving, modulation and other communication processes was designed by Matlab/Simulink. Ultimately, the signal I/Q data the signal power spectrum were obtained. At the same time, the reliability of the simulation was verified through the analysis. Of bit error rate and block error rate
