Title (EN) INTER-BAND DISTORTION AND INTERFERENCE MITIGATION WITHIN COMMUNICATION SYSTEMS
(FR) ATTÉNUATION DE DISTORSION ET D'INTERFÉRENCE INTER-BANDES DANS DES SYSTÈMES DE COMMUNICATION
Abstract:
(EN) A wireless communication device includes one or more transmitter (TX)-receiver (RX) pairs, one or more RX distortion estimators, and a combiner. A first RX distortion estimator receives a first TX signal corresponding to a first TX of the first TX-RX pair and a second TX signal corresponding to a second TX of a second TX-RX pair. The first RX distortion estimator processes the first TX signal and the second TX signal based on a first base function set including at least one base function to generate a first distortion signal set including at least one distortion signal. Then, the first RX distortion estimator processes the first distortion signal set to generate a first RX correction signal. The wireless communication device's combiner generates a first distortion compensated RX signal by compensating for distortion in a first RX signal of the first TX-RX pair based on the first RX correction signal.
(FR) La présente invention concerne un dispositif de communication sans fil qui comprend une ou plusieurs paires d'émetteurs (TX)-récepteurs (RX), un ou plusieurs estimateurs de distorsion RX, et un combinateur. Un premier estimateur de distorsion RX reçoit un premier signal TX correspondant à un premier TX de la première paire TX-RX et un second signal TX correspondant à un second TX d'une seconde paire TX-RX. Le premier estimateur de distorsion RX traite le premier signal TX et le second signal TX sur la base d'un premier ensemble de fonctions de base comprenant au moins une fonction de base afin de générer un premier ensemble de signaux de distorsion comprenant au moins un signal de distorsion. Ensuite, le premier estimateur de distorsion RX traite le premier ensemble de signaux de distorsion afin de générer un premier signal de correction RX. Le combinateur du dispositif de communication sans fil génère un premier signal RX à compensation de distorsion par compensation de la distorsion dans un premier signal RX de la première paire TX-RX sur la base du premier signal de correction RX.
