Opportunities exist to explore Baseband Diversity Products (BDP) with flexibility options to operate in contested environments to maintain connectivity, improve link availability, reliability, and resilience, while at the same time confounding adversarial attempts to intercept and/or detect communications signals in wideband satellite communications. The implication of the diversity via satellite transponders, non-contiguous bandwidths, coverage beams, signal polarizations, and multiple media, is that baseband traffics such as video, voice, and data could be disintegrated and integrated according to dedicated and/or opportunistic network path flows for optimal end-to-end latency, transmission reliability, information security, and bandwidth utilization. This topic seeks to develop new approaches for innovative data stream splitter supervised by link information feedback (e.g., data rates, latency, modulation, channel coding) and quality of services per applications; adaptive load balancing for multipath routing and flow control with best efficiency and reliability; and agile code/frequency/time-hopping transmission patterns for satellite communications with low probability of detection and interception, as well as multiple link flow security.
If successful, the BDP technologies anticipated for future terminal communications, which will be inserted in between routers and satellite modems, should be capable of (1) supporting multiple network topologies for high speed data, voice, and video communications over terrestrial and satellite networks and (2) processing multiple streams simultaneously and interfacing with multiple commercial and military modems to support anti-jamming enhancement and ease of integration.
