Method for carrier residue suppression, using vector modulator for conversion of base band signal, consisting of in-phase and quadrature components, into complex output signal

摘要

To appliance, containing vector modulator, is supplied component of base band signal as signal with constant level and first polarity during first time interval (T1) and first mean signal amplitude of output signal determined.One component of base band signal is supplied as signal with constant level and second polarity during second time interval (T2) and second mean signal amplitude determined difference between both signal amplitudes of output signal is formed and offset value of baseband signal determined. Determined offset value is added to, or subtracted from component at constant signal.
