DIGITAL INCOHERENT SIGNAL DEMODULATOR WITH AMPLITUDE QUATERNARY PHASE-SHIFT KEYING Russian patent published in 2021 - IPC H04B1/10 H04L27/38 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and can be used in digital apparatuses for receiving information signals with combined amplitude and relative phase quaternary phase-shift keying. The digital incoherent signal demodulator with amplitude quaternary phase-shift keying comprises an analogue-to-digital converter (ADC), a four-count multi-digit code shift register (SR4), a first and a second n-cascade channels for quadrature signal processing (QSP), a clock pulse generator (CPG), a first and a second register memory apparatuses (RMA), a first, second, third and fourth digital multipliers (DM), a first and a second adding apparatuses (AA), a first and a second subtracting apparatuses (SA), a first and a second computing apparatuses (CA), a decoder (DC), a quadratic converter (QC), a clock synchronisation unit (CSU), a threshold former (TR), a signal level decision forming unit (DFU), and a code former (CF).

EFFECT: increase in the speed of information transmission.
