软件无线电硬件体系结构研究

软件无线电具有开放性、标准化、模块化和高度可编程的特点,被认为是继模拟通信技术、数字通信技术之后的第三代无线通信技术.在了解传统无线电体系结构的基础上,首先简单介绍了软件无线电体系结构的演化过程：数字无线电、软件定义无线电、理想软件无线电以及虚拟无线电.然后,详细总结了目前软件无线电硬件体系结构的两种常用实现--流水线式、总线式结构的特点.最后,引入目前研究的新方向--交换式及基于工作站簇的结构.

A Study of Software Radio Hardware Architecture

Software radio, which is called the third generation of wireless communication technology, is an open, standard, modularized and programmable system. Based on the analysis of analog radio system, the developing history of software radio architecture is introduced, including digital radio, software defined radio, ideal software radio and visual radios. Then some implement modes of software radio hardware architecture are mainly discussed, including platforms based on pipeline, buses, switch and cluster of workstations, in which platforms based on pipeline and buses are common used today, and others are still scientific research subjects in labs.
