The increasing demand for beyond-line-of-sight and in-transit space communications is leading to an emerging growth for secure and resilient communications. Specifically, handling efficiently jamming resistance, low probability of interception, low probability of detection, etc. is essential for future capability enhancements expected from Wideband Global SATCOM (WGS). In this research opportunity, modeling, simulation and analysis associated with ground hub satellite system controllers are being investigated to account for (1) dynamic resource allocation enabled by competitive decision-making frameworks for radio resources and link margin assignments that can best respond for airborne and/or ground terminals in presence of radio interferences and in accordance of channel-state information feedback and (2) forward and return link multiple accesses supported by universal modulation and demodulation techniques together with frequency-time burst approaches to transport existing WGS waveforms through contested environments.
