Software Communications Architecture
The Software Communications Architecture (SCA) is an open architecture that regulates the interaction of hardware and software in software-modifiable radio stations (software defined radios, SDRs ). SCA was mainly developed by the US military and forms the core of the Joint Tactical Radio System . The main task is to monitor the structure and function of the JTRS, to specify programmable radio elements for variable transmitters and receivers and to ensure interoperability.
A so-called core framework is a requirement for SCA hardware. This is what makes portability possible. The main integration areas for SCA are currently FPGAs and DSPs .
The Object Management Group (OMG) has founded a Domain Special Interest Group for software radios (SWRADIO DSIG) with the aim of standardizing SCA for commercial purposes.
