Title (EN) SYSTEM AND METHOD FOR SEPARATING SIGNALS RECEIVED BY AN OVERLOADED ANTENNA ARRAY
(FR) SYSTEME ET PROCEDE DE SEPARATION DE SIGNAUX REÇUS PAR UN RESEAU D'ANTENNES SURCHARGE
Abstract: front page image
(EN)A method of separating mixed wireless signals is provided. The method includes receiving, at an antenna comprising a first quantity of antenna elements, mixed signals comprising a mixture of source signals communicated from a second quantity of wireless signal sources, and separating the mixed signals to estimate the source signals. The second quantity is greater than the first quantity, and the source signals communicated from at least one of the wireless signal sources are received at the antenna as complex signals.
(FR)L'invention porte sur un procédé de séparation de signaux hertziens mixtes, ce procédé consistant à recevoir, au niveau d'une antenne comprenant une première quantité d'éléments, des signaux mixtes comprenant un mélange de signaux sources envoyés depuis une seconde quantité de sources de signaux hertziens, et à séparer les signaux mixtes afin d'estimer les signaux sources. La seconde quantité est supérieure à la première, et les signaux sources envoyés depuis au moins une des sources de signaux hertziens sont reçus au niveau de l'antenne sous forme de signaux complexes.
