METHOD FOR ADAPTIVE RE-REFLECTION OF SIGNAL STAR PATTERNS IN PROCESS OF QUADRATURE-AMPLITUDE MODULATION FOR REPEATED TRANSFERS OF DATA PACKETS Russian patent published in 2010 - IPC H04L1/18

Abstract RU 2391782 C1

FIELD: information technologies.

SUBSTANCE: circuit of simplified character-oriented re-reflection of signal star patterns QAM applies preference of separated bits of I and Q indication in QAM signal to reduce complexity of receiving unit. The present invention also proposes method for adaptive switching between bit-oriented and character-oriented re-reflection of star patterns in process of data packets transfers carried out in compliance with coefficient of channel coding to achieve optimal working characteristics within the range of channel coding speeds.

EFFECT: improved quality of working characteristics with high coding coefficient.
