基于开源SDR实现LTE系统对比

Comparisons of LTE system based on open-source SDR

本文首先介绍现有的两套开源软件无线电系统,OAI和Open LTE。经过调试将OAI和Open LTE在通用软件无线电硬件平台上成功运行,重点分析了现有两套系统实现方法的异同,对两套系统的实现功能完整性进行了全面分析。本文结论将为研究LTE系统和下一代无线通信技术的科研人员提供新的理论研究参考。

This paper presents two kinds of open-source SDR softwares, OAI and Open LTE. They can be run successfully on hardware USRP after debugging. The different ways to implement the two systems can be analyzed. Then the integrities about the two systems according to the results can be compared. They can provide new platforms of theoretical verification for the researchers on the LTE system or the next generation wireless communication system.
