摘要:
A scheme for localizing a wireless user equipment (UE) device's relative position with respect to a spatial configuration (101, 201) based on audio signatures received via a multi-channel audio system, e.g., an audio system of a vehicle (106A-106D) or home entertainment system (204A-204D). The wireless UE device (500) is configured to capture the audio signatures masked within a background audio signal received from a head unit (102, 202). The wireless UE device (500) includes a persistent memory module (535) having program instructions for processing the background audio signal including the masked signatures, which may comprise either channel-specific pseudo-random noise (PN) sequences or single-frequency tones, in order to compute time delays or power levels associated with the speaker channels. A localization module (550) is configured to estimate the wireless UE device's relative position based on the time delays or power levels.
摘要(中):
一种用于基于经由多声道音频系统(例如,车辆的音频系统(106A-106D))接收的音频签名来定位无线用户设备(UE)设备相对于空间配置(101,201)的相对位置的方案 )或家庭娱乐系统(204A-204D)。 无线UE设备(500)被配置为捕获从头单元(102,202)接收的背景音频信号中屏蔽的音频签名。 无线UE设备(500)包括具有用于处理包括掩蔽的签名的背景音频信号的程序指令的持久存储器模块(535),其可以包括信道专用伪随机噪声(PN)序列或单频音调, 以便计算与扬声器通道相关联的时间延迟或功率电平。 定位模块(550)被配置为基于时间延迟或功率电平来估计无线UE设备的相对位置。
