摘要： Phase of an output signal is based on comparison of an oscillating signal with an adjustable threshold. Here, adjustment of the threshold results in a corresponding adjustment of the phase of the output signal. For example, the adjustable threshold may comprise an adjustable bias signal for a transistor circuit whereby the oscillating signal is provided as an input to the transistor circuit and the output of the transistor circuit provides the output signal. In some aspects these phase adjustment techniques may be employed to provide one or more tunable multiphase clocks.

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： 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 tunable delay line is calibrated to maintain the delay of the delay line at a desired value or within a desired range of values. In some aspects a signal is passed through a delay line multiple times so that the cumulative delay of the signal through the delay line (e.g., as indicated by a count) may be calculated over a period of time. The count is compared with an expected count and, based on this comparison, the delay of the delay line is adjusted as necessary. In some aspects the signal may comprise a digital signal. In some aspects a delay through a delay line may be calculated based on analysis of amplitude changes in a signal caused by a phase shift imparted on the signal by the delay line. In some aspects a delay line is incorporated into a transmitted reference system to generate and/or process transmitted reference signals.

摘要： A leading edge associated with a received signal is detected to provide, for example, time of arrival information for a ranging algorithm. In some aspects, a method of leading edge detection involves sampling a received signal, generating a drift compensated signal based on the samples, reconstructing the received signal based on the drift compensated signal, and identifying a leading edge associated with the received signal based on the reconstructed signal.

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： An apparatus for data communication that receives a plurality of pulses from a remote communications device, determines a pulse puncturing rate based on the pulses, and punctures or discards subsequent pulses based on the pulse puncturing rate. During intervals when punctured pulses are expected, the apparatus operates in a lower power consumption mode for the purpose of conserving power. In another aspect, a receiving apparatus determines the pulse puncturing rate based on received pulses, and transmits the pulse puncturing rate information to a transmitting apparatus. In response, the transmitting apparatus sends a subset of the pulses it would have transmitted based on the pulse puncturing rate. Because the receiving apparatus receives fewer pulses (e.g., a subset), the receiving apparatus may operate in a lower power consumption mode for longer periods in order to conserve power. Similarly, because the transmitting apparatus sends fewer pulses, it may also operate in a lower power consumption mode for longer periods.
摘要翻译：一种用于从远程通信设备接收多个脉冲的数据通信装置，基于脉冲确定脉冲打孔速率，并且基于脉冲打孔速率对后续脉冲进行穿刺或丢弃。在期望脉冲脉冲的间隔期间，为了节省功率，该装置以较低的功耗模式工作。在另一方面，接收装置基于接收到的脉冲来确定脉冲打孔速率，并将脉冲打孔速率信息发送到发送装置。作为响应，发送装置基于脉冲打孔速率发送其将发送的脉冲的子集。由于接收装置接收到更少的脉冲（例如，子集），所以接收装置可以在较低的功耗模式下操作更长的时间段，以便节省功率。类似地，由于发送装置发送较少的脉冲，所以它也可以在较低的功耗模式下工作较长时间。
