Radio transmission for information signals uses fragmentation of spectrum to overcome noise and jamming effects

摘要

The system includes removal of corrupt spectral components prior to transmission of the signal. The system provides perfect transmission of a modulated signal with spectrum (Sw) allowing reconstruction of the modulating signal (s(t)) and its perfect correlation function (c( tau )). The system uses a technique of fragmentation of the spectrum, consisting of locating, at transmission, the spectrum of the signal except for the contaminated parts of the spectrum. The spectrum obtained (Smf(w)) is compressed at reception, and an adaptive device corrects the effects caused by the fragmentation, and allows reconstruction without deformation of the signal (rma(t) and the correlation function (cms( tau )).
