DEVICE FOR GENERATING SIGNALS WITH MULTI-POSITION MANIPULATION Russian patent published in 2019 - IPC H04L27/32

Abstract RU 2688135 C1

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to digital radio communication and can be used in information transmission systems by means of noise immunity of signals with multi-position manipulation. Signal generation device with multi-position manipulation generates signal with sixteen-position manipulation, which is a sum of two four-position quadrature phase shift keying (QPSK) signals at two orthogonal frequencies with localized spectrum, wherein signal constellation point of generated signal is encoded by first and second frequencies and two signal vectors of QPSK signal.

EFFECT: increased noise immunity of signals with multi-position manipulation at limited frequency resource.
