A process for the carrier radical determination in a vector modulator arrangement, including

摘要

A method for determining a carrier radical in a vector modulator arrangement, including, in which the vector modulator for conversion of a an in-phase component and a quadrature component in the baseband signal comprising a complex output signal is formed and in which the arrangementa) one of the components of the baseband signal as a signal (+ i) with sections with a constant level and a first polarity during a first time interval (t1) and fed to a first average signal amplitude of the output signal is determined;b) the said one of the components of the baseband signal as a signal (– i) with sections with a constant level and a second polarity during a second time interval (t2) and fed to a second average signal amplitude of the output signal is determined;c) with the formation of a difference between the first and second signal amplitude, an offset is - value of the a component of the baseband signal is determined.
