Cet article présente la méthode d'analyse et d'identification du système Wiener-Hammerstein pour caractériser un émetteur RF non linéaire dans la zone de fréquence fondamentale. Un signal bicolore est utilisé pour analyser et identifier un modèle Wiener-Hammerstein. Un signal RF est converti en signal complexe équivalent en bande de base, et le modèle de Wiener-Hammerstein est considéré comme ayant des filtres polynomiaux et linéaires complexes équivalents en bande de base. Pour un signal d'entrée à deux tons, des descriptions sous forme fermée du signal de sortie dans le domaine temporel et le domaine fréquentiel sont développées à l'aide de phaseurs à deux tons à modulation non linéaire (NMTP) récemment suggérés. La relation entre les termes de fréquence des signaux d'entrée et de sortie dans les émetteurs RF est représentée par une équation matrice-vecteur linéaire basée sur l'analyse NMTP. Un avantage de la méthode proposée est sa simplicité utilisant l’analyse de forme fermée et l’approximation linéaire. De plus, nous pouvons modéliser un système à large bande avec des mesures à bande relativement étroite en balayant un signal à deux tons. La prédiction de la repousse spectrale et les performances de prédistorsion pour le signal WiBro 1FA démontrent la validité de l'approche proposée pour identifier les émetteurs RF non linéaires.

Abstract: This paper presents analysis and identification method of Wiener-Hammerstein system to characterize a nonlinear RF transmitter in fundamental frequency zone. A two-tone signal is used to analyze and identify a Wiener-Hammerstein model. A RF signal is converted to baseband-equivalent complex signal, and Wiener-Hammerstein model is considered to have a baseband equivalent complex polynomial and linear filters. For a two-tone input signal, closed form descriptions of the output signal in the time domain and frequency domain are developed using a newly suggested nonlinearly modulated two-tone phasors (NMTP). The relationship between frequency terms of input and output signals in RF transmitters are represented with linear matrix-vector equation based on NMTP analysis. An advantage of the proposed method is its simplicity using closed form analysis and linear approximation. In addition, we can model a wideband system with relatively narrowband measurements by sweeping two-tone signal. The prediction of spectral regrowth and the predistortion performance for WiBro 1FA signal demonstrate the validity of the proposed approach in identifying the nonlinear RF transmitters.
