FIELD: technology for processing data before transmission.
SUBSTANCE: method includes stages: control signal is received for adjusting one of parameters: amplification coefficient and shift current, - of circuit element, connected to transmission signal route, while adjusted aforementioned parameter causes phase rotation in data signal in aforementioned route, and provides for maintained phase turn compensation value, appropriate for operation state, set by received control signal, while maintained phase turn compensation value is approximately of the same value and opposite direction relatively to phase turn value, caused by adjusted parameter, and phase rotation is performed of at least one of a) data signals, b) expanding series for expanding spectrum of aforementioned data signal, and c) bearing signal for modulation of data signal, by means of stored phase compensation value.
EFFECT: compensation of phase turn, caused by adjustment of adjustable circuitry elements, in signal transfer route.
