<p>The invention relates to methods for transceiving discrete (digital) information. In the claimed method, a transmitting side uses a function having a limited spectrum as an information pulse signal envelope, said function having, in one or a plurality of intervals within a pulse, oscillations with a frequency that exceeds the cutoff frequency of the modulated pulse spectrum as a whole (frequency surges), wherein the parameter values for these oscillations are associated with the informative feature of the signal to be transmitted, and on the receiving side, the received combination of signal and noise is split, following processing in the frequency band of the modulated pulse signal and up to the demodulator, into elementary pulse signals having a duration equal to the duration of the interval with a frequency surge, which elementary pulse signals are subjected to frequency-filtering processing or spectral processing within a frequency band which is determined by the interval with a frequency surge; by identifying this interval (or intervals) and then analyzing the parameters of the oscillations with a frequency surge, the value of the informative feature in the received modulated signal is determined.</p> |
