- 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.
