LTE-A空口监测分析仪射频接收的设计与实现

Design and Implementation of RF Reveive for LTE-A Air-Interface Monitoring Analyzer

随着LTE网络的商用化,国际范围内迫切需要空口监测类仪表,研发符合3GPP及行业标准要求的LTE-A空口监测仪表对我国后续建设及优化LTE网络具有重要意义。该文从系统的层面介绍了设备的物理架构和逻辑架构设计,以射频基带板、层二处理板、主控板及系统时钟板等板卡组成设备的硬件结构。然后从各板卡的信息交互方面设计了仪表的工作流程。最后通过搭建测试平台,验证了LTE-A空口监测分析仪射频接收性能。

With the commercialization of LTE networks,air-interface monitoring instruments are urgently needed in the international area.It is of great significance to develop LTE-A air-interface monitoring instruments that meet the requirements of 3GPP and industry standards for China's subsequent construction and optimization of LTE networks.This paper introduces the physical architecture and logical architecture design of the device from the systemlevel.The hardware structure of the device is composed of the RF baseband board,the layer 2 processing board,the main control board and the system clock board.Then,the workflow of the instrument is designed from the information interaction of each board.Finally,the RF reception performance of the LTEA air interface monitoring analyzer was verified by building a test platform.
