METHOD AND COMMUNICATION SYSTEM WITH FAST ACQUISITION BY ULTRA-WIDEBAND SIGNALS Russian patent published in 2009 - IPC H04B7/00 

FIELD: physics.

SUBSTANCE: cycle of native data and exchange data establishment is realised in UWB receiver and transmitter, UWB pulses synchronous messages are radiated by transmitter, calibrating cycle is realised, as well as cycle of input UWB pulses searching by receiver, acquisition of receiver and transmitter with further working cycle, at that transmitter radiates synchronising or information sequence of phase-shift keying or frequency-shift keying signal, in search cycle input phase-shift keying or frequency-shift keying signal is amplified, its spectrum is transferred to intermediate frequency in high-frequency unit and intermediate frequency of phase-shift keying or frequency-shift keying receiver, transformed into digital form, processed by wavelet-filter, which shapes video pulses and synchronises unit of synchronisation of time slots of UWB receiver shaping sequence of pulses that strobe unit of time slot and follow its clock frequency that coincides with synchronising sequence of radiated UWB pulses, sequence of video pulses from output of wavelet-filter are also decoded with separation of video pulse that corresponds to code of synchronous parcel, afterwards receiver acquires accordingly UWB receiver and phase-shift or frequency-shift keying transmitter. System comprises common part, transmitting part and receiving part, receiving part comprises noiseless amplifier, attenuator, power splitter, time slot unit of signal channel, signal channel threshold device, signal channel buffer device, control and processing unit, noise channel time slot unit, noise channel threshold device, noise channel buffer device, unit of high and intermediate frequency, analog-to-digital transducer, wavelet-filter, synchronisation unit, decoder, shapers of threshold voltages of signal channel and noise channel.

EFFECT: increased rate of acquisition of communication system with the possibility to separate phase-shift or frequency-shift information.
