Digital distortion compensation for wideband direct digitization RF receiver

Résumé

This paper deals with the study of a new correction structure for the distortion compensation in direct digitization receivers. In that purpose, a modified post-distortion algorithm including an efficient adaptive filter is used. Performance have been demonstrated on measurements from a state of the art wideband TI-ADC and from an entire direct-digitization RF receiver. On the TI-ADC, with a two-tone input signal, the algorithm has improved the SFDR by ∼ 25dB. Besides, Besides, on the entire receiver, the algorithm has been able to achieve ∼ 16dB of improvement on the SFDR.
