Abstract: front page image
(DE)Ein Verfahren zur gleichzeitigen Kompensation mehrerer in einem IQ-Modulator (2) auftretender Signalfehler mit jeweils dazu inversen Korrektursignalen (Gain_I, Gain_Q, Offset_I, Offset_Q, Quadratur) ermittelt die optimierte Signalgrösse jedes Korrektursignals (Gain_I, Gain_Q, Offset_I, Offset_Q, Quadratur) durch Bestimmung des effektiven Signalfehlers und durch anschliessende Minimierung des effektiven Signalfehlers iterativ.
(EN)The invention relates to a method for the simultaneous compensation of several signal errors that occur in an IQ-modulator (2), using respective inverse correction signals (Gain_I, Gain_Q, Offset_I, Offset_Q, Quadrature). According to the method, the optimised signal magnitude of each correction signal (Gain_I, Gain_Q, Offset_I, Offset_Q, Quadrature) is calculated by the determination of the effective signal error and by the subsequent iterative minimisation of the effective signal error.
(FR)La présente invention concerne un procédé de compensation simultanée de plusieurs erreurs de signal apparaissant dans un modulateur de IQ (2) avec des signaux de correction respectivement inverses (gain_I, gain_Q, décalage_I, décalage _Q, quadrature). Ce procédé consiste à détecter l'amplitude de signal optimisée de chaque signal de correction (gain_I, gain_Q, décalage_I, décalage _Q, quadrature) en déterminant l'erreur de signal effective, puis en minimisant cette erreur de signal effective de manière itérative.
