Executive Impact: Elevating Autonomous Systems' Perception
SoM-MIMO represents a significant leap forward for enterprise applications requiring robust, real-time environmental awareness. Its capabilities directly address critical challenges in dynamic, data-intensive operational environments.
Executive Summary: Transforming Enterprise Perception with SoM-MIMO
Traditional image transmission methods struggle in low Signal-to-Noise Ratio (SNR) scenarios typical of B5G/6G mobile agent networks, leading to a 'cliff effect' where performance rapidly degrades. This paper introduces SoM-MIMO, a breakthrough system that deeply integrates image instance segmentation tasks with digital Multiple-Input Multiple-Output (MIMO) communication. By employing hierarchical feature fusion, channel-aware encoding, and nonlinear feature activation, SoM-MIMO ensures highly accurate and robust perception even under adverse channel conditions, while maintaining efficient data transmission. This translates into enhanced operational reliability and improved decision-making capabilities for autonomous systems.
- Enhanced Perception Accuracy: Achieve average mAP improvements of over 10% across all SNR levels, critical for real-time applications like autonomous driving.
- Superior Robustness: Overcome traditional "cliff effect" with a system designed for resilience against fading channels and noise, ensuring reliable operation in complex environments.
- Optimized Communication Efficiency: Reduce feature data volume by over 95% and provide flexible compression ratios (e.g., 1/16 to 1/768) without significant performance degradation.
- Native Digital MIMO Compatibility: Seamlessly integrate with existing digital MIMO infrastructure through standard baseband processing and learnable nonlinear activation.

Understanding the Bottleneck: Robust Sensory Data Transmission
In B5G/6G environments, mobile agents require real-time, accurate environmental perception, largely reliant on RGB images. However, dynamic scenarios introduce challenges like occlusions and harsh conditions, leading to missed detections and false positives. Collaborative Perception (CP) necessitates high-speed, robust sensory data transmission, a critical but often unmet challenge due to the limitations of current communication systems.
Traditional coding schemes (JPEG, LDPC) suffer from a 'cliff effect' under adverse channel conditions, leading to rapid degradation or failure. While deep learning-based Joint Source-Channel Coding (JSCC) offers improvements, existing MIMO JSCC schemes are often limited to the discrete-time analog transmission (DTAT) model, neglecting integration with digital MIMO systems, and focus on image reconstruction quality (PSNR/SSIM) rather than downstream perceptual tasks. This gap significantly hinders their utility for complex CP tasks.

SoM-MIMO: A Synesthetic Approach to Digital Perception
Inspired by human synesthesia, the Synesthesia of Machines (SoM) framework intelligently integrates multi-modal information. SoM-MIMO applies this by jointly encoding MIMO channel information and image data into compact, task-aware, and robust 'SoM-features'. This unique integration enables efficient and reliable digital MIMO transmission specifically designed for challenging perceptual tasks like instance segmentation.
The system's core innovations include a Hierarchical Feature Fusion (HFF) module that significantly reduces data redundancy (over 95%) by intelligently combining multi-scale feature pyramids. An MIMO Channel-aware Encoding (MCE) module then leverages physical layer information (SNR, CSI) to adaptively distribute features across MIMO sub-channels, boosting robustness. Finally, nonlinear feature activation is integrated into standard digital MIMO baseband processing, ensuring seamless compatibility and stability under bit errors.

Case Study: Autonomous Vehicle Cooperative Perception
Imagine a fleet of autonomous vehicles navigating a complex urban intersection during heavy fog. Each vehicle's local sensors provide partial, often degraded, image data. With SoM-MIMO, these vehicles can efficiently and robustly transmit critical instance segmentation data (e.g., location and type of pedestrians, cyclists, other vehicles) to a central fusion point or neighboring vehicles. The SoM-MIMO's channel-aware encoding ensures that even under severe signal attenuation, the most critical features for obstacle detection are prioritized and reliably delivered. This dramatically improves the shared environmental model, enabling safer and more precise collaborative decision-making, such as predicting pedestrian movements or coordinating multi-vehicle maneuvers, far beyond what any single vehicle could achieve independently.
Quantified Impact & Strategic Enterprise Roadmap
Our experimental results, validated on the high-resolution Cityscapes dataset, demonstrate SoM-MIMO's superior performance for instance segmentation. Compared to leading JSCC baselines, SoM-MIMO achieves average mAP improvements of 6.30% to 10.48% across all SNR levels, while maintaining identical communication overhead. Crucially, at low SNR (-5dB), our scheme delivers up to 16.83% higher mAP, proving its resilience in challenging conditions.
The system's adaptability is further demonstrated by its flexible Compression Ratio (CR) from 1/16 to 1/768, allowing enterprises to balance communication overhead and perception performance based on specific operational needs. The integration of channel-aware encoding and digital baseband processing ensures that this performance is achieved within standard digital MIMO communication frameworks, making it readily deployable for B5G/6G applications.
