Abstract: Various methods, apparatuses and/or articles of manufacture are provided which may be implemented in one or more electronic devices supporting mobile device positioning within an indoor environment. Tiered positioning assistance data (tiered-PAD) corresponding to an indoor environment may be generated and/or distributed. Mobile device positioning and/or navigation capabilities may be based, at least in part, on tiered-PAD corresponding to the indoor environment. Tiered-PAD may be provided to a plurality of mobile devices. A given mobile device may, for example, select applicable portion(s) of tiered-PAD to affect one or more positioning functions and/or the like which may be performed, at least in part, by the mobile device.

Abstract: Techniques are provided for deriving speed estimates by performing a convolution of the output of the Fast Fourier Transform (FFT) stage from different time windows in an orthogonal frequency-division multiplexing (OFDM) modulation scheme. Such techniques enable speed estimation to be performed in the frequency domain, requiring little or no modification to existing OFDM systems.

Abstract: System and methods are disclosed to use ultrasonic (US) and WiFi signals to improve range determination between devices in WiFi-based position or range estimation systems. Such systems may leverage existing WiFi infrastructure and US-capable sensors such as speakers and microphones as US transducers. US ranging between devices may be performed using round-trip time (RTT) or one-way measurements. To enable US ranging between a device and multiple US transmitters simultaneously, the US signal from each US transmitters or from the device may be modulated with a unique pseudo-random number (PRN) using direct sequence spread spectrum (DSSS). The transmission of US signals may be synchronized with the transmission of WiFi beacons which may contain data fields that contain the PRN sequence used to modulate the synchronous US signal. In RTT ranging, a receiving device receiving an US signal transmission may respond with its own PRN-modulated US signal synchronized to its WiFi beacon.

Abstract translation: 公开了使用超声波（US）和WiFi信号来提高基于WiFi的位置或距离估计系统中的设备之间的距离确定的系统和方法。 这样的系统可以利用现有的WiFi基础设施和美国传感器，例如扬声器和麦克风作为US换能器。 可以使用往返时间（RTT）或单向测量来执行设备之间的美国范围。 为了使美国同步在美国和多个美国发射机之间进行测距，可以使用直接序列扩频（DSSS），使用独特的伪随机数（PRN）来调制来自每个US发射机或从设备的美国信号。 US信号的传输可以与可能包含包含用于调制同步US信号的PRN序列的数据字段的WiFi信标的传输同步。 在RTT测距中，接收美国信号传输的接收设备可以利用与其WiFi信标同步的其自己的PRN调制的US信号进行响应。
