DIGITAL BINARY SIGNAL DEMODULATOR WITH SECOND-ORDER RELATIVE PHASE MANIPULATION

摘要

FIELD: radio engineering and communications.;SUBSTANCE: invention relates to radio engineering and can be used in devices for receiving digital information signals for digital demodulation of binary signals with relative phase manipulation of second order (RPM2). Digital signal demodulator with relative phase manipulation of the second order comprises an analogue-to-digital converter (ADC), a shift register of multibit codes for four readings, first and second n-cascade quadrature signal processing channels (QPC), a clock pulse generator (CPG), a first and a second reading unit (RU), each of which consists of a first and a second multi-bit shift register, first, second and third adders, first, second and third subtractors and a decision-forming unit (DFU), comprising first, second, third and fourth quadratic converters (QC), first, second and third subtractors, first and second multiplexers and a trigger.;EFFECT: providing high-speed digital demodulation of signals with relative phase manipulation of the second order.;1 cl, 5 dwg
