AI 中文摘要
超低延迟通信对于XR、实时控制和分布式传感等新兴下一代应用至关重要。我们提出ECO-COMM，一种基于事件相机的超低延迟设备关联与轻量信息交换光通信系统。通过利用事件相机的异步传感和微秒级时间分辨率，ECO-COMM可捕获高频光信号，无需基于帧的采集延迟。我们识别并分析了事件相机通信中由硬件引发的关键挑战，包括时间戳不一致、读出竞争、拖尾效应以及不可避免的不应期，并开发了感知硬件的缓解技术来解决这些问题。针对单发射机-接收机光链路，ECO-COMM验证了使用商用硬件实现实用超低延迟事件相机通信的可行性。采用8个LED发射机和现成事件相机的原型实现，设备关联耗时15微秒，符号延迟低至100微秒，32字节有效载荷的端到端延迟低于8毫秒，误码率为0.1%。ECO-COMM为对响应性和时间精度至关重要的超低延迟系统建立了一种实用且互补的通信范式。
英文摘要
Ultralow-latency communication is critical for emerging next-generation applications such as XR, real-time control, and distributed sensing. We present ECO-COMM, an event-camera-based optical communication system for ultra-low-latency device association and lightweight information exchange. By exploiting the asynchronous sensing and microsecond-level temporal resolution of event cameras, ECO-COMM captures high-frequency optical signals without frame-based acquisition delays. We identify and analyze key hardware-induced challenges in event-camera communication, including timestamp inconsistency, readout contention, trailing effects, and the inevitable refractory period, and develop hardware-aware mitigation techniques to address them. Focusing on a single transmitter-receiver optical link, ECO-COMM establishes the feasibility of practical ultra-low-latency event-camera communication using commercially available hardware.A prototype implementation using an eight-LED transmitter and an off-the-shelf event camera achieves device association within 15 microseconds, symbol latency as low as 100 microseconds, and end-to-end latency below 8 milliseconds for 32-byte payloads at 0.1% bit error rate. ECO-COMM establishes a practical and complementary communication paradigm for ultra-low-latency systems where responsiveness and temporal precision are paramount.
