ASYNCHRONOUS-CEPSTRUM METHOD OF EXTRACTING ENCODED INFORMATION SENT TO USER USING ULTRA-WIDEBAND PULSES Russian patent published in 2011 - IPC H04B1/69 H04J13/00 

FIELD: radio engineering.

SUBSTANCE: when encoding information, an ultra-wideband signal is used, consisting of nanosecond duration pulses described by a Gaussian function first-order derivative. The sequence of these pulses will include pulses following with a fixed period called ''reference" pulses, as well as pulses in between the reference pulses called "central" pulses. Logic "zero" or "one" encoding information will be contained in the time position of the "central" pulses relative "reference" pulses. These pulse delays are determined based on cepstrum processing and the time delays determined this way are then converted to a sequence of logic "zeroes" and "ones".

EFFECT: reliability of extracting information.
