基于射频拉远的软件无线电接收机设计

Design and Optimization of Software Radio Receiver Based on Remote Radio Technique

射频拉远是一种新型的分布式网络覆盖模式。其基本思想是将基带部分集中处理,而射频模块则采用单模光纤拉到远端射频单元,从而节省了大量机房,便于管理,维护,同时拓展了网络覆盖面积。该文结合当今数字处理器件的实际水平,给出了基于宽带中频采样方式的接收机结构设计方案,并仿真验证了其可实现性。

Remote radio technique is a new overcast model of distributed network.It’s central idea is to make cen-tralized processing of the base band signal,while using single mode fiber to pull RF modules to RRU,so as to save a large number of machine rooms,easy for management and maintenance,and also expand the network coverage area.By considering the practical level of digital data processor nowadays,this paper provides a design proposal of software radio receiver based on broadband IF sampling,and simulation of i...
