MAGIC(R)-COINS (CO-channel INterference Separation): Comprehensive Interference Mitigation and Capacity Optimization for Tactical Data Links

Adaptive Dynamics, Inc. proposes GOLD-COINS, (Generalized OrthogonaL Decomposition)-(CO-channel INterference Separation), a robust, reconfigurable and resource-efficient architecture that first decomposes a wideband input with arbitrary sub-band allocations into a bank of filters, which then separate multiple co-channel interferers within each bank.  An initial 3-channel prototype design for GOLD-COINS has been tightly coupled with the GEMINI-IMPS (Generalized Excision of Multiple INput Interference)-(Integrated Massively Parallel Separator) interference mitigation system under development for single-antennas under contract N68335-19-C-0258 (IMPS) and for dual-antennas under SBIR topic N192-D03 (GEMINI-IMPS).  The prototype algorithm has demonstrated reliable performance in extremely challenging contested / congested operating conditions with an astounding 50-67% increase in capacity. The proposed work may increase capacity up to 100%, and is projected to fit within available hardware resource budgets.
