Integrated Wideband Spectral Management / Satellite Receiver Modem

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) system"s 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 SATCOM"s 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.
