Abstract

Modern wireless systems enables multiuser scheduling via channel quality feedback. While these systems apply the modulation and coding optimization for a SISO channel, in this paper, we consider the multiuser scheduling problem in a matrix modulated MIMO channel. It is shown that in a MIMO channel appreciable scheduling, gains can be achieved only if the channel quality measurement reflects the inter-stream interference induced by matrix modulation. Moreover, it is seen that multiuser diversity paves the way for a low-complexity receivers in matrix modulated MIMO channels.
