摘要： In a two-way ranging scheme where a first apparatus (e.g., device) determines a distance to a second apparatus (e.g., device), specified packets are sent between these apparatuses at specified times to facilitate the determination of the distance. In some aspects, these packets may be defined and/or sent in a manner that enables the apparatuses to detect a leading edge of a received packet with a high degree of accuracy. For example, an apparatus may transmit a packet a defined period of time after transmitting or receiving another packet. In addition, a packet may comprise a defined symbol sequence that is used by an apparatus that receives the packet to identify a leading edge of the packet.

摘要： Low power wireless communication techniques may be employed in devices that communicate via a wireless body area network, a wireless personal area network, or some other type of wireless communication link. In some implementations the devices may communicate via one or more impulse-based ultra-wideband channels. Inter-pulse duty cycling may be employed to reduce the power consumption of a device. Power may be provided for the transmissions and receptions of pulses by charging and discharging a capacitive element according to the inter-pulse duty cycling. Sub-packet data may be transmitted and received via a common frequency band. A cell phone may multicast to two or more peripherals via wireless communication links.

摘要： A channel access scheme is provided for a pulse-based ultra-wide band network. Here, concurrent ultra-wide band channels may be established through the use of a pulse division multiple access scheme. An access scheme may employ different states each of which may be associated with different channel parameter state information and/or different duty cycles. For example, a channel access scheme may employ an inactive state, an idle state, a connected state, and a streaming state. Multiple logical channels may be defined for a given ultra-wide band channel via, for example, pulse division multiplexing.

摘要： In a signal-based gain control scheme, one or more gain levels used for processing signals are selected based on characteristics of previously received signals. For example, different gain levels may be used to receive sets of signals whereupon certain characteristics of the received sets of signals are determined. One or more gain levels are then selected based on these characteristics whereby another signal is processed based on the selected gain level(s). In some aspects, the signal-based gain control scheme may be employed to facilitate two-way ranging operations between two devices. For example, leading edge detection may involve determining a characteristic of a received signal, determining a threshold based on the characteristic, and identifying a leading edge associated with the received signal based on the threshold. In some aspects, the signal-based gain control scheme may be employed in an ultra-low power pulse-based communication system (e.g., in ultra-wideband communication devices).
摘要翻译：在基于信号的增益控制方案中，基于先前接收到的信号的特性来选择用于处理信号的一个或多个增益电平。例如，可以使用不同的增益电平来接收信号集合，从而确定所接收的信号组的某些特性。然后基于这些特征选择一个或多个增益电平，由此基于所选择的增益电平处理另一个信号。在一些方面，可以采用基于信号的增益控制方案来促进两个设备之间的双向测距操作。例如，前沿检测可以涉及确定接收信号的特性，基于特性确定阈值，以及基于阈值来识别与接收信号相关联的前沿。在一些方面，基于信号的增益控制方案可以用于基于超低功率脉冲的通信系统（例如，在超宽带通信设备中）。
