摘要
随着无线通信的附属领域已经达到相对成熟的阶段,针对运营商网络优化手段不足的问题,LTE-A空口监测分析仪可以丰富通信网络测试的手段并突破了国内空口监测仪表的技术瓶颈。通过对LTE-A物理层的研究,仪表的研发设计方案需要增加测试对比,基于3GPP协议开发的仿真平台即满足仪表的性能指标。该仿真平台主要以LTE-A物理层下行链路为主,基于MATLAB模拟产生数据源解析用来研究、对比及场外测试LTE-A空口监测分析仪FPGA的解析实验结果。根据FPGA的实现要求数据定点化对该仿真平台中浮点型数据解析过程进行定点化处理保证译码的准确性,解析结果的呈现保证了监测仪表的节点数据的实时状况,通过该方案可加快网络测试方案的部署并对运行维护起到了支撑的作用。
As the sub-area of wireless communication has reached a relatively mature stage, the LTE-A air interface monitoring analyzer can enrich the means of communication network testing and break through the technical bottleneck of domestic air interface monitoring instruments. Through the research of LTE-A physical layer, the design scheme of instrument needs to increase test comparison. The simulation platform based on 3GPP protocol meets the performance index of instrument. The simulation platform is mainly based on the LTE-A physical layer downlink. Data source analysis based on MATLAB simulation is used to study, compare and test the results of the LTE-A air interface monitoring analyzer FPGA. According to the requirement of the implementation of the FPGA, the floating-point data analysis process in the simulation platform is fixed-point processed to ensure the accuracy of decoding. The presentation of the analysis results ensures the real-time status of the node data of the monitoring instrument. Through this solution, the deployment of the network test solution can be accelerated and the operation and maintenance can be supported.
