The Software Communications Architecture (SCA) is an open architecture framework that tells designers how elements of hardware and software are to operate in harmony within a software defined radio. SCA governs the structure and operation of the U.S. military's Joint Tactical Radio System (JTRS), enabling programmable radios to load waveforms, run applications, and be networked into an integrated system. A Core Framework, providing a standard operating environment, must be implemented on every hardware set. Interoperability among radio sets is enhanced because the same waveform software can be easily ported to all radio sets.
The Object Management Group (OMG), a not-for-profit consortium that produces and maintains computer industry specifications for interoperable enterprise applications, has established a Software Based Communications Domain Task Force (SBC-DTF). This group and the Wireless Innovation Forum (formerly Software Defined Radio Forum) (WINNF), are working on an international commercial standard based on the SCA.
The SCA is extending its coverage to programmable hardware FPGA and digital signal processors.

Famous quotes containing the word architecture:
“It seems a fantastic paradox, but it is nevertheless a most important truth, that no architecture can be truly noble which is not imperfect.”
—John Ruskin (1819–1900)
