摘要： Systems and methods are disclosed that provide pulse-level interleaving for multi-pulse-per-bit ultra wideband (UWB) transmit and receive processing techniques to provide significantly improved multi-access for UWB systems and, more particularly, for long range UWB systems. A bit stream is processed such that each bit in a bit stream is represented by a plurality of bits in a bit frame and then transmitted using a plurality of UWB pulses for each bit frame. Where on-off-keying (OOK) modulation is used, each logic “1” is sent out as a plurality of pulses, and each logic “0” is sent out as a plurality of non-pulses. Pulse-level interleaving (PLI) of the pulses across multiple bit frames prior to transmission is provided to allow for improved multi-access (MA) by a plurality of UWB transmitters operating at the same time. Rather than attempt to detect each pulse as it arrives at the receiver, the receiver instead first de-interleaves the pulses and then aggregates the energy from the multiple pulses within each bit frame. The aggregated pulse energy is then processed by a pulse detector to detect a pulse. Where OOK modulation is used, this pulse detection detects the existence of a pulse or the lack of a pulse within the bit frame.

摘要： A RFID tag system may be configured as a tag having a first band (e.g., multiple channel-based NBFM frequency band) transceiver to allow field programmability of tag behavior and onboard tag data. The RFID tag system may be configured to collect data from one or more local sensors through the first band link and store data points of interest in tag onboard storage. The RFID tag system may be configured to work in conjunction with a remote interrogating unit, and a handheld device or other local interrogating unit may be additionally or alternatively provided to communicate with such aRFID tag. Data that is stored on the RFID tag may be retrieved or changed, and/or the operation of the tag may be modified.

摘要： Systems and methods for generating pulsed output signals that employ a gated RF oscillator circuit having an output that is switchably grounded through the emitter of a transistor and including feedback from the output of the circuit to the base of the transistor to create oscillations and to allow a digital input pulse of a desired length to control the start and stop of oscillations created by the transistor.
