FIELD: radio engineering.
SUBSTANCE: device for high-speed data transmission using digital modulation and frequency hopping spread spectrum in node for the formation of modulating quadrature signals I(t) and Q(t) contains a two-channel digital computing synthesizer (DCS), which generates signals with a frequency offset in both directions from the zero frequency. The claimed device uses instantaneous tuning of FHSS (Frequency Hopping Spread Spectrum) due to the properties of a digital computing synthesizer, and also uses predefined profiles of digital computing synthesizer for operational frequency change at FHSS and coherence of the carrier output frequency with clock frequency of data source and DCS.
EFFECT: creation of more efficient and reliable high-speed data transmission device using various types (FSK, PSK, QAM) of digital modulation and frequency hopping spread spectrum with a simple functional scheme, simple algorithms for the formation of signal-code structures, the ability to work without time pauses required for frequency adjustment, increased secrecy.
