【摘要】 介绍了SDR电台的开放系统结构——软件通信体系结构,在依据SCA3.0开发的开放环境基础上,完整实现了特定应用的FM3TR波形;从SDR电台的实时性、软件实现的角度,对FM3TR波形传送数据与话音两种情况进行了测试。结果表明,基于SCA开发的SDR电台,有着良好的互操作性及软件的可移植性,并能够满足诸如话音通信等实时性要求不高的业务需求。更多还原

【Abstract】 This paper studies on software communication architecture,an open system architecture used for SDR.It realizes an application-specific FM3TR waveform based on the open environment of SCA3.0.From the point of real-time performance of SDR and software implementation,tests are made on FM3TR waveform under the environment of data and voice communication.As a result,the SCA-compliant SDR has favorable interoperability and software portability and can meet the real-time performance requirements such as voice communication.更多还原
