摘要： A high-speed transmitter and receiver are provided. In one embodiment, a transmitter comprises a baseband processor structured to receive data and to convert the data into a multiplicity of high and low signal values, with each high and low signal value having a first timing interval. A local oscillator generates a clock signal at a second timing interval and a digital circuit combines the high and low signal values with the clock signal to produce a transmission signal directly at a transmission frequency. A receiver is configured to receive the signal. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

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 signal to be transmitted is modified. An ultra wideband (UWB) signal to be transmitted is obtained, the UWB signal having a data carrying sub-band and a non data carrying sub-band. Information in the non data carrying sub-band is modified so that the power associated with the non data carrying sub-band is less than the power prior to the modification. Information in the data carrying sub-band is modified so that the power associated with the data carrying sub-band is greater than the power prior to the modification. The amount by which the data carrying sub-band increases in power is based at least in part on the amount by which the non data carrying sub-band decreases in power. A UWB signal is transmitted having the modified information in the non data carrying sub-band and the modified information in the data carrying sub-band.

摘要： In a mobile environment, a mobile device includes an attached memory stick (removable memory) having a high speed—memory and storage with direct memory access embodied in an integrated circuit chip coupled to an ultra-wideband (UWB) transceiver. The mobile device communicates with other like base devices, portable or stationary, via UWB transmissions using pulse bursts up to 1 Gbit per second. Data transfers between the devices occur in the simplex or duplex mode, after a low power communication connection is established between the devices. The communication link between the devices is in the range of 10-20 meters. The communication system allows existing device bus interfaces (which are much slower than ultra-wideband transmissions) to communicate between the fast read/write cycles of the memories integrated within the memory stick. Duplex transmission can occur by pulse interleaving sending side transmitters and receiving side transmitters.
