Interference cancellation is implemented for a multiple antenna system. The multiple antenna receiver is provided that includes a whitening filter coupled to receive processed signals corresponding to signals received at respective antennas, and to generate whitened signals corresponding to each of the received signals, having a colored noise component whitened. The whitening filter coupled to determine the whitened signals, at least in part, utilizes symbols corresponding to the signals received by the plurality of antennas. A signal separator is coupled to supply the whitening filter with processed received signals having interference components reduced as compared to received signals.
La présente invention concerne l'annulation d'interférence pour un système à antennes multiples. Le récepteur à antennes multiples comprend un filtre de blanchiment couplé pour recevoir des signaux traités correspondant à des signaux reçus au niveau d'antennes respectives et pour produire des signaux blanchis correspondant à chacun des signaux reçus, ayant une composante de bruit coloré blanchie. Le filtre de blanchiment couplé pour déterminer les signaux blanchis, au moins en partie, utilise des symboles correspondant aux signaux reçus par la pluralité d'antennes. Un séparateur de signal est couplé pour fournir au filtre de blanchiment les signaux reçus traités ayant des composantes d'interférence réduites par rapport aux signaux reçus.
