Resumen:
o 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.
