UHF SATCOM Wideband Interference Mitigation

In our Phase I program, SA Photonics developed a complete concept design for the DICE SATCOM interference cancellation Applique which supports both UFO and MUOS systems. The developed concept design includes a detailed digital and RF hardware design, top level FPGA and DSP architectures. At the heart of DICE are very innovative, completely blind interference cancellation algorithms. To validate our design and algorithms, we developed an extensive end-to-end MUOS simulator including high precision satellite orbits, MUOS signal generator, full channel and impairment models, implementation of the DICE algorithms, and a complete MUOS receiver including despreader and demodulator. This extensive simulation effort allowed us to perform a detailed validation of our processing algorithms and concept design. In this Phase II program SA Photonics will finalize the processing algorithms and develope a complete DICE prototype system. The goal is to perform extensive testing on the prototype unit with MUOS radios and simulators in order to validate the performance in real-world-operational environments.
