一种实现VEM总线结构的软件无线电方案

摘要

为了解决无线电通信领域内多体系并存、不同体系间无法制订统一标准等问题．在介绍了软件无线电提出的背景、硬件系统结构和软件系统结构的基础上，采用WiMAX802．16技术给出了一种实现VEM总线结构的软件无线电基站方案，以便满足用户在任何时间、地点的通信需求。研究了其对多种软件无线电标准的适应性，能够覆盖多个频段，能进行软件重构和复用。%To solve the problems that multiple systems coexist in radio communication field and no unified standards are established between different systems. Base on the introduction of background, hardware system structure, software system structure, the application in mobile terminal units and base station,the base station structure for WiMAX802.16 were introduced which realizes the VEM bus structure enabling customers to communicate with their radio environment at anytime and anywhere, It is also introduced in its adaptability to multiple standards and coverage of multiple frequency-band as well as being re-programmable.
