dc.description.abstract | In this paper, we propose a new beamforming scheme
that generates beams by exploiting the spatial correlation in multiuser environments. The proposed scheme generates random beams using eigenvectors corresponding to dominant eigenvalues of the channel covariance matrix, increasing the multiuser diversity gain. Moreover, it can obtain an additional SNR gain by transmitting the signal with a beam weight coherent to the effective channel corresponding to dominant eigenvectors of the channel covariance matrix of a selected user. Simulation results show that the proposed scheme is quite effective in correlated channel environments. | en |
