Abstract

In this paper we present efficient MIMO transceiver architectures evaluated in a multiuser environment. In this context we consider traditional MIMO transmit structures and also hybrid ones proposed in [6] capable of achieve diversity and multiplexing gains. Our results shown that in a multiuser environment the MIMO transmit structures of the desired user has a crucial impact in the performance due the diversity orders of the multiple layers in the MIMO structure.
