A method and apparatus is described for generating a standard software communication architecture (SCA) compliant waveform application for a software defined radio. An application shell generator is used to separate implementation of software radio software resources from implementation of software radio waveform functionality. In this manner, an additional layer of abstraction is defined and enforced between software resource objects that control access to a set of physical abstraction layer SCA core framework API's and waveform functionality. This additional abstraction layer assures that the physical abstraction layer API's only interact with architecture compliant source code. The source code, derived from software resource templates, also assures portability of the generated software radio waveform application to other SCA compliant platforms.

Disclosed is a system and method for operating a domain profile using a database in a core framework for an SDR terminal. In the core framework for an SDR terminal, which has an SCA (software communications architecture)-based software structure, several managers record domain profiles required to install and execute applications on a database text file, instead of recording the domain profiles on an XML file, and then store the database text file in a database and manage the domain profile.

In this way, it is possible to reduce parsing time and improve the performance of a system.
