To improve the spectrum efficiency in wireless MIMO systems, it is   essential to mitigate     the channel interference. Opportunistic   scheduling of multiusers and interference     cancellation, such as   adaptive multiuser detection, are two commonly used techniques.     In   this paper we study the performance improvement of using jointly these   techniques     for enabling the use of the same set of spreading codes   to transmit two data streams     in closed loop multiuser MIMO systems.   We show that with the proposed scheduling schemes,     the performance   of an Adaptive Blind Receiver (ABR) is not degraded when the scheduled  users share the same spreading code.
