Title (EN) NON-LINEAR PRODUCT DETECTION AND CANCELLATION IN A WIRELESS DEVICE
(FR) DÉTECTION DE PRODUIT NON LINÉAIRE ET ANNULATION DANS UN DISPOSITIF SANS FIL
Abstract:
(EN) An apparatus and method for cancelling and/or attenuating one or more signal impairments included within a transmitted RF signal is disclosed. In at least one exemplary embodiment, a baseband signal is generated based, at least in part, on a predicted impairment signal subtracted from a desired baseband signal. An impairment detection signal may be generated by multiplying the predicted impairment signal by the baseband signal. The predicted impairment signal may be adjusted based, at least in part, on the impairment detection signal.
(FR) L'invention concerne un appareil et un procédé d'annulation et/ou d'atténuation d'au moins une dégradation de signal incluse dans un signal RF émis. Dans au moins un mode de réalisation donné à titre d'exemple, un signal de bande de base est généré en fonction, au moins en partie, d'un signal à dégradation prédite soustrait d'un signal de bande de base souhaité. Un signal de détection de dégradation peut être généré en multipliant le signal à dégradation prédite par le signal de bande de base. Le signal à dégradation prédite peut être ajusté en fonction, au moins en partie, du signal de détection de dégradation.
