The Software Communications Architecture (SCA) is an open architecture framework that defines a standard way for radios to instantiate, configure, and manage waveform applications running on their platform. SCA uses standard Application Programming Interfaces (APIs) to define the key software interfaces that allow the waveform application and radio platform to interact. The SCA separates waveform software from the underlying hardware platform, facilitating waveform software portability and re-use to avoid costs of redeveloping waveforms. The latest version is SCA 4.1.


Overview

A software-defined radio's transmitter can be changed through software, not hardware, to alter frequency range, modulation type, and maximum radiated or conducted output power. The Software Communication Architecture (SCA) outlines several interfaces, which describe what operations the various components can be made to do.
