Title (EN) ZERO-CROSS-PRE-DISTORTION (ZCPD) ALGORITHM FOR DTC BASED POLAR DTX
(FR) ALGORITHME DE PRÉDISTORSION À PASSAGE PAR ZÉRO (ZCPD) POUR DTX POLAIRE À BASE DE DTC
Abstract: front page image
(EN)Devices and methods of compensating for a bandpass filter are generally described. A DTx includes a BPF from which an output signal is produced and a DFE having a zero crossing (ZC) pre-distorter (ZCPD). The ZCPD compensates for ZC distortion from a desired analog signal caused by the BPF. The ZCPD adjusts a DTC code word to generate a DTx output signal to be applied to the BPF. The compensation is dependent on a magnitude of the square wave immediately prior to and after the ZC. The compensated DTC and a DPA code word are used to generate the DTx output signal. The compensation produced by the ZCPD is free from compensation for non-linear responses to the DTC and DPA code words.
(FR)L'invention concerne de façon générale des dispositifs et des procédés de compensation pour un filtre passe-bande. Un DTx comprend un BPF à partir duquel un signal de sortie est produit et un DFE comportant un dispositif de prédistorsion à passage par zéro (ZC) (ZCPD). Le ZCPD compense la distorsion de ZC d'un signal analogique souhaité provoquée par le BPF. Le ZCPD ajuste un mot de code de DTC pour produire un signal de sortie de DTx à appliquer au BPF. La compensation dépend d'une amplitude de l'onde carrée immédiatement avant et après le ZC. Le DTC compensé et un mot de code de DPA sont utilisés pour produire le signal de sortie de DTx. La compensation produite par le ZCPD est exempte de compensation pour des réponses non linéaires aux mots de code de DTC et de DPA.
