Abstract
The invention relates to a multiantenna radio communications method wherein frequency subbands Bs, for k=1, . . . , P, are allocated respectively to P user antennas s1, . . . , sp belonging to one or more users, from within a total frequency bandwidth BT, and wherein at least one of the user antennas communicates with the base station over its respective frequency subband Bsby means of a signal that has been filtered by time reversal. According to the invention, for at least one pair of user antennas Si and Sj, where and i,j=1, . . . , P and i≠j, the respective frequency subbands Bsand Bsoverlap by δBs,s, said overlap δBs,sbeing a predetermined function of the correlation between the respective propagation channels of these two user antennas with said base station.
