摘　　要：介绍了软件无线电的概念和结构,针对传统软件无线电实现方案,提出一种基于SOPC技术的中频软件无线电解决方案。系统采用基于NiosII软核处理器的SOPC技术,在ALTERA公司的FPGA上实现了片上系统。基于SOPC技术的软件无线电系统具有极高的灵活性、可扩展性,这充分体现了软件无线电的设计思想。This article introduces the concept and structure of software radio. In contrast with traditional scheme forimplementation of software radio system, it introduces a kide of solution to IF software radio system based on SOPC technology.This paper implements a soc （system-on-chip） which applies the SOPC technology based on Nios II softcore processors in a piece of ALTERA＇s FPGA. The software radio system based on SOPC technology has very high flexibility and expansibility which fully reflects the essence of software radio.
