We study the multiuser diversity with constellation selection based on a virtual representation of realistic MIMO correlated channels.To realize multiuser diversity in slow fading correlated channels
We adopt random beamforming technique and propose to construct random beamforming matrix exploiting virtual channel representation.Simultaneously
adaptive coded modulation is applied to each sub-channel of the selected user to improve the system performance further.Two cases are considered:minimizing the BERs in each sub-channel and maximum the sum of data rate.
