FIELD: information technology.
SUBSTANCE: asynchronous wavelet-cepstral method of selecting encoded information sent to user using packets of ultra-wideband pulses. The objective of the invention is: a) providing reliable selection of information in form of logic "zeros" and "ones" when sending messages using ultra-wideband pulses in a mode which does not require their synchronisation, with signal-to-noise ratio of not less than 2 dB; b) enabling use of ultra-wideband pulses of arbitrary shape in a code sequence of packets of ultra-wideband pulses by reducing the logarithmic nonlinearity effect in a cepstral processing algorithm.
EFFECT: high reliability of selecting received information through reverse wavelet signal recovery without coefficients which carry information on low-frequency changes in the logarithm of the energy spectrum of the received signal.
