Abstract
The invention relates to a multiantenna radio communications method wherein frequency subbands B, for k=1, . . . , P, are allocated respectively to P user antennas s, . . . , sbelonging to one or more users, from within a total frequency bandwidth B, and wherein at least one of the user antennas communicates with the base station over its respective frequency subband Bby means of a signal that has been filtered by time reversal. According to the invention, for at least one pair of user antennas Sand S, where and i,j=1, . . . , P and i≠j, the respective frequency subbands Band Boverlap by δB, said overlap δBbeing a predetermined function of the correlation between the respective propagation channels of these two user antennas with said base station.
