L-Band RF IM & Measurement Applique for POES/GOES

In Phase 1, Adaptive Dynamics Inc. (ADI) propose to do a PHY layer MATLAB simulation and optimization of the 'IMPS' Wideband MAGIC® Interference Mitigation (IM) filter for NOAA. This will demonstrate the feasibility and performance of the IMPS Wideband MAGIC® IM filter algorithm in effectively identifying and separating out unwanted interference from the desired signal of interest (SOI), without 'a priori' knowledge of the interference or SOI. In this case, the SOI's are NOAA GOES/POES downlink received QPSK SATCOM signals and the unwanted interference comes from terrestrial-based Long-Term Evolution (LTE) Orthogonal Frequency Division Multiplex (OFDM) uplink mobile user wireless signals in the 1695-1710 MHz band. As part of the MATLAB simulation, ADI propose to develop an algorithm to automatically alarm when undesired interference is detected and to characterize the interference type and severity. Additionally, ADI propose to do a demo of the Comtech CDM-MAGIC930, an L-Band real-time interference mitigation and data capture/playback applique for SATCOM signals developed under a Navy Rapid Innovation Funding (RIF) contract. If a Phase 2 contract were awarded, ADI would then implement the optimized IMPS MAGIC® interference mitigation algorithm into suitable FPGA hardware for the NOAA L-Band SATCOM application.
