Unveiling MIMO Potential: A Prototype for Enhanced Tactical Communications with Interference Suppression
This paper examines the implementation of multi-user massive MIMO technologies within wireless tactical ad-hoc networks in contested environments. By developing a real-time 8-antenna MIMO-OFDM prototype that supports SDMA communications under multiple jamming signals, we introduce innovative algorithmic solutions for interference mitigation and enhanced SDMA capabilities. These include a novel frame structure for reliable synchronization in multipath conditions and an adaptive MMSE interference suppression equalizer/receiver suitable for firmware implementation. Our findings, validated through field trials, demonstrate significant improvements in jamming suppression, offering a robust framework for secure and efficient tactical communications.
