METHOD OF INVERSE-QUADRATURE RESTORATION OF CARRIER FREQUENCY PHASE-SHIFT KEYED SIGNALS OF ANY FREQUENCY RATE

摘要

FIELD: physics; radio. ^ SUBSTANCE: invention concerns radio engineering and can be used at demodulation of PSK signals of various frequency rates. The essence of the method is characterised by restoration of carrier frequency of the phase-shift keyed signals by forming of inverse-quadrature components of the inphase and quadrature channels with use of the tunable oscillator of sinusoidal fluctuations on the doubled frequency concerning carrier frequency of a received phase-shift keyed signal. ^ EFFECT: increase of noninterference and maintenance of carrier restoration at any frequency rate of phase-shift keyed (PSK) signals. ^ 5 dwg
