SIXTEEN-POSITION QUADRATURE KEYING SIGNAL RECEIVER Russian patent published in 2004 - IPC

Abstract RU 2234815 C1

FIELD: radio engineering; reception of quadrature amplitude keying signals.

SUBSTANCE: signal undergoes following procedures: coherent carrier frequency is recovered from output quadrature amplitude keying signal in first carrier recovery unit; carrier frequency recovered in first unit is used as reference oscillation during coherent demodulation of input coherent amplitude keying signal in first demodulator; carrier frequency recovered in second recovering unit is used as reference oscillation during coherent demodulation of input coherent amplitude keying signal in second demodulator.

EFFECT: enhanced noise immunity in signal reception due to enhanced reliability of false phase capture detection and elimination.
