Innovations drive our Research and Development capabilities. SSC’s engineers combine creativity with technical expertise to develop groundbreaking solutions to some of the hardest spectrum sharing problems.

Dynamic Spectrum Access

SSC is the world’s leader in Dynamic Spectrum Access (DSA), having developed a mature suite of DSA software that enables greater communications performance and operational effectiveness. Our DSA capabilities include planning tools and real-time software running on a radio. SSC’s DSA increases communications network reliability and resiliency in congested and contested RF environments by adapting radio waveform characteristics and network operations in response to local operating conditions, mission needs, and defined spectrum access rules. Our DSA solution enables spectrum managers and mission planners to codify sets of spectrum access rules and mission-specific needs into rulesets that the radio’s DSA Engine evaluates in real-time to automate spectrum maneuver in distributed and centralized control architectures. SSC’s DSA reduces the overhead and time required for spectrum planning and operations, enabling a faster and more agile command and control. Our DSA provides the foundation for increasing spectrum sharing with reduced coordination and automating PACE (Primary, Alternate, Contingency, and Emergency) operations.

Cognitive Radio

 

SSC has developed and demonstrated Cognitive Radio Technologies in numerous commercial and tactical radio systems for terrestrial and satellite communications. SSC was the first to successfully field test a prototype cognitive radio system (August 16, 2006), which implemented a first-ever sensing-based Dynamic Spectrum Access (DSA) capability on an 802.16 standard. SSC has since partnered with radio developers to transform standard wideband tactical networking radios and 5G prototypes into spectrum-agile cognitive radio platforms. Our prototypes have been demonstrated in DoD land, littoral, airborne, and at sea environments.

Spectrum Sensing

SSC is a recognized leader in spectrum measurements and RF analyses. We conducted numerous spectrum measurements and analyses that laid the foundation for early government investments in DSA research and development. We use spectrum measurements in conjunction with RF propagation models to establish statistical characterizations of phenomena such as clutter and anomalous propagation that impact spectrum sharing. We also conduct spectrum analyses to characterize, identify, and geo-locate interference sources. Our spectrum sensing supports the development of spectrum situational awareness and exploitation (e.g., spectrum maneuver) capabilities.

Simulation and Analysis

 

SSC develops and uses a wide range of simulation and analysis tools for spectrum analysis, DSA and wireless network performance evaluation, and development of advanced signal processing algorithms. SSC’s unique capabilities include a Virtual Node Environment, which enables us to evaluate real-time DSA radio code performance in large-scale scenarios. We also developed simulation models that generate and evaluate spectrum sharing rules across numerous environments characterized by complex terrain, clutter, and atmospheric anomalous propagation conditions. SSC can also evaluate DSA network performance in specific operational scenarios to demonstrate and evaluate mission performance improvements resulting from improved spectrum access and communications system performance associated with DSA.

Lab & Field Testing

SSC’s test and evaluation experience spans from engineering component testing to operational field testing. Our state of the art lab facilities provide engineers with the tools needed for system prototyping and evaluation. We have field tested system prototypes across a range of environments and locations including DoD test ranges (e.g., Yuma Proving Grounds, Ft. AP Hill, Ft. Dix, and Ft. Irwin) and across the US in various urban, suburban, and rural locations.
