摘　　要：该文主要研究了基于软件通信体系结构(SCA)的软件定义无线电(SDR)系统设计与实现。首先介绍了SCA的相关背景,然后根据SCA的标准设计了基于SCA的SDR系统硬件平台、硬件抽象层(MHAL)、核心框架、波形软件的实现技术方案,最后通过测试波形对该系统的实时性能进行测试和分析。结果表明:基于SCA的SDR系统互操作性和波形可移植性得到很大提高,实时性能可以满足实际应用需求,但依旧是系统的性能瓶颈。This paper analyzes the design and implementation of the software defined radio （SDR） system based on the software communication architecture （SCA） whose background was first introduced. The schemes were then given based on the SCA standards for the implementation of the hardware platform, software platform, modem hardware abstraction layer （MHAL） and waveform software. Tests were made to investigate the system real-tlme performance. The results show that the SCA-compliant SDR has favorable interoperability and software portability and can basically satisfy the requirements of real-time performance which is still a bottleneck of the system performance.
