[Feature] Extend to Multi-Channel / MIMO

📌 Motivation

The current prototype demonstrates adaptive interference cancellation in a single-channel scenario.
To align with 6G ISAC use-cases, extending to multi-channel and MIMO systems is a natural next step.

🎯 Goal

• Generalize FxLMS prototype to handle multiple input/output streams
• Investigate joint optimization strategies for beamforming and interference suppression
• Explore performance scaling as the number of antennas increases

💡 Potential Approaches

• Implement multi-dimensional filter updates
• Compare centralized vs. distributed adaptation schemes
• Benchmark against existing MIMO interference cancellation techniques

✅ Expected Outcomes

• A baseline MIMO-capable extension in src/
• Benchmark results showing improvements in SINR for 2x2 and 4x4 systems

Thanks for opening this feature track! 🚀
Multi-channel is a natural extension, and I think starting with a 2x2 MIMO baseline would make sense.
Anyone interested in collaborating on this, feel free to propose initial approaches!
