Low-Overhead Software Communications Architecture ( SCA) Core Framework (CF) for Small Form Factor (SFF),Low-Power Software Defined Radios (SDRs)

The Software Communications Architecture (SCA) defines an architecture for a common radio system infrastructure. This infrastructure or Core Framework provides the management and control capabilities for a radio system. However, many SCA projects have resulted in large, monolithic implementations that do not scale well across a range of radio systems. Thus, it has not been successfully applied to Small Form Factor (SFF) radio systems that have stringent Size, Weight and Power (SWaP) constraints. Objective Interface Systems believes that the fundamental architecture defined by the SCA specification is valid and that a different perspective on the design and implementation is necessary to achieve deployment of the SCA across a wider range of platforms. Coupled with innovative technology for automated removal of unreferenced code and modular deployment architecture, this SBIR project will identify specific driving requirements for SFF radio systems. Specific design and implementation optimizations will be identified together with anticipated improvements. Several of these optimizations will be implemented to gather quantitative data on the benefits of the approach. The result of the Phase I effort will be a comprehensive plan for an SCA core framework implementation that both meets the SCA specification and the deployment profile demands of the SFF radio.
