CA 2278532

In a cellular communication network, capacity in a cell is increased by placing antennas transmitting different signals on the same carrier frequency at separated locations in the cell, rather than at the center of the cell. A receiver includes multiple antennas and uses spatial diversity, such as beamforming and cancellation, to extract the desired signal.

L'invention porte sur réseau cellulaire de télécommunications dans lequel il est possible d'accroître la capacité d'une cellule en disposant des antennes émettant différents signaux sur la même fréquence porteuse en des points distincts de la cellule, plutôt qu'au centre de la cellule. L'invention porte également sur un récepteur à plusieurs antennes utilisant la diversité spatiale, pour la formation et l'annulation du faisceau, afin d'extraire le signal désiré.
