与消费类设备的高数据速率近超声波通信
High Data Rate Near-Ultrasonic Communication with Consumer Devices
摘要：
在消费类设备中实现设备配对和凭证交换的自动化可减少用户处理日常任务的时间，并改善用户体验。声学通信作为蓝牙或Wi-Fi的实用替代方案正在获得关注，因为它可以在具有内置硬件的消费者设备之间实现快速和本地化的信息传输。然而，在这样的系统中实现高数据速率（>1 kbps）一直是一个挑战，因为选择用于通信的系统和方法不是针对应用定制的。在这项工作中，提出了一种高数据速率的近超声波通信（NUSC）系统，用于传输个人识别码（PIN），以使用内置麦克风和扬声器在消费者笔记本电脑之间建立连接。室内近超声波和水声通信（UWAC）信道之间的相似性被确定，和适当的UWAC技术是量身定制的NUSC系统。该系统使用18-20 kHz的近超声频段，并采用相干调制和相位相干自适应均衡。所提出的系统的能力，探讨在模拟和现场实验，跨越不同的设备方向和距离。实验表明，在长达5米的距离上的数据速率为4 kbps，这是一个数量级高于文献中类似系统报告的数据速率。
英文摘要：
Automating device pairing and credential exchange in consumer devices reduce the time users spend with mundane tasks and improve the user experience. Acoustic communication is gaining traction as a practical alternative to Bluetooth or Wi-Fi because it can enable quick and localized information transfer between consumer devices with built-in hardware. However, achieving high data rates (>1 kbps) in such systems has been a challenge because the systems and methods chosen for communication were not tailored to the application. In this work, a high data rate, near-ultrasonic communication (NUSC) system is proposed to transfer personal identification numbers (PINs) to establish a connection between consumer laptops using built-in microphones and speakers. The similarities between indoor near-ultrasonic and underwater acoustic communication (UWAC) channels are identified, and appropriate UWAC techniques are tailored to the NUSC system. The proposed system uses the near-ultrasonic band at 18-20 kHz, and employs coherent modulation and phase-coherent adaptive equalization. The capability of the proposed system is explored in simulated and field experiments that span different device orientations and distances. The experiments demonstrate data rates of 4 kbps over distances of up to 5 meters, which is an order of magnitude higher than the data rates reported with similar systems in the literature.
