摘要

本文介绍了一种基于块的无速率信道编码形式，通过减少信道编码的开销和延迟来最大限度地减少能量消耗。因此，用于增强现实(AR)的蓝牙(IEEE 802.15.1)可穿戴无线网络的结果显示，与蓝牙FEC方案相比，能耗一致降低。AR依赖于可穿戴网络上的视频传输。面对日益恶化的信道条件，在头戴式显示器上，与基于块的FEC相比，基于块的无速率编码在视频质量方面提高了约5db。系统建模考虑了生物传感器产生的交叉流量，这些传感器根据佩戴者的认知负荷调节AR显示。

Rateless coding on a wearable wireless network for Augmented Reality and biosensors

This paper introduces a block-based form of rateless channel coding that minimizes energy consumption by reducing the overhead and latency from channel coding. Consequently, results from a Bluetooth (IEEE 802.15.1) wearable wireless network for augmented reality (AR) show a consistent reduction in energy consumption compared to Bluetooth FEC schemes. AR relies on video transmission across a wearable network. Block-based rateless coding resulted in around 5 dB improvement compared to block-based FEC in video quality at a head-mounted display in the face of worsening channel conditions. System modeling took into account cross-traffic resulting from biosensors that moderate the AR display according to the cognitive load of the wearer.
