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 matched filter and peak detector identify peaks of a received signal. The peak detector may detect peaks during a fixed or adjustable time window. The peaks may be used as a preliminary decision (e.g., soft decision) for subsequent receiver decoding operations. The detector may be used to detect high bandwidth signals such as ultra-wide band signal pulses yet consume relatively minimal power.

摘要： A signaling scheme employs transmitted reference pulses having varying phase. The phase of the reference pulses may be varied in a random manner or in accordance with a data stream. In some aspects a transmitter modulates the phase of the reference pulses to encode an additional data stream in a transmitted reference signal. In some aspects these techniques are employed in a heterogeneous network including coherent and non-coherent receivers. In some aspects these techniques may be employed in an ultra-wide band system.

摘要： Various techniques are described relating to verifying a distance between devices. A distance between two devices may be verified by requiring one of the devices to take one or more actions that generate a result that is only possible if the device is at most a given distance from the other device. In some aspects verified ranging is accomplished through the use of a ranging signal and a responsive signal. In some aspects the ranging signal may comprise a random, pseudorandom, or deterministic sequence. A responding device may operate on a ranging signal in accordance with a known function to generate a responsive signal. A ranging device also may perform operations to determine the likelihood that a responding device properly operated on a ranging signal that the ranging device transmitted to the responding device.
摘要翻译：描述了关于验证设备之间的距离的各种技术。两个设备之间的距离可以通过要求设备中的一个进行一个或多个动作来验证，该动作只有在设备距离其他设备至多一定距离时才可能产生。在一些方面，验证的测距通过使用测距信号和响应信号来实现。在一些方面，测距信号可以包括随机，伪随机或确定性序列。响应设备可以根据已知功能在测距信号上操作以产生响应信号。测距设备还可以执行操作以确定响应设备在测距设备正确地操作测距设备发射到响应设备的可能性。
