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.
