A diversity receiver (300) has improved diversity weighting parameter. The receiver different versions of a signal (101) having encoded data, combines the versions and decodes the data contained within the combination. The decoded data out-put is then re-encoded using a similar technique as that at a transmitted which transmitted the signal (101). The re-encoded data is then used to calculate a diversity weighting which is used to modify a stored replica of each version. The modified versions are then combined and decoded to yield a more accurate estimate of the information contained within the signal (101) at diversity receiver (300).

Un récepteur en diversité (300) offre un paramètre amélioré de pondération en diversité. Les différentes versions reçues d'un signal (101) porteur de données codées combinent les versions et décodent les données contenues dans la combinaison. La sortie de données décodée est ensuite recodée selon une technique semblable à celle de l'émetteur d'où provient le signal (101). Les données recodées servent ensuite à calculer une pondération en diversité, utilisée pour modifier une réplique stockée de chaque version. Les versions modifiées sont ensuite combinées et décodées, ce qui donne une estimation plus exacte de l'information contenue dans le signal (101) au récepteur en diversité (300).
