Applying Cognitive Radio and adaptive Software-Defined Radio technologies, combined with next-generation Analog-to-Digital Converters and digital signal processors will substantially improve future Satellite Communication (SATCOM) systems overall performance by providing better real-time visibility into the RF operating environment, enabling automatic channelization to improve spectral efficiency, and mitigate the effects from RF interference. The key technologies required to monitor and respond to the RF external environment by necessity reside proximal to the SATCOMs physical layer, including mechanisms to obtain spectral awareness and to provide adaptive spectral allocation and utilization. The Digital Signal Processing based spectrum monitoring and channelization technologies being proposed are independent of modulation scheme and will be an ideal solution for supporting future SATCOM applications.
Benefit: This project will improve the bandwidth efficiency and link performance of DOD and commercial satellite and terrestrial communication systems. The growth in mobile wireless and SATCOM data communications is largely driven by broadband internet access and the increasing use of rich media (video, IPTV, etc.) streamed over IP networks is driving an exponential growth in mobile data traffic. This growth will be paralleled to a large degree by the growth in commercial SATCOM platforms.
