User Assignment for MIMO-OFDM Systems with Multiuser Linear Precoding
— Recent work has developed single-carrier linear precoding for the multiuser downlink for multiple-input multipleoutput (MIMO) systems. This paper addresses the problem of user ...

Low complexity MIMO scheduling with channel decomposition using capacity upperbound
Abstract In multiuser MIMO systems, the base station schedules transmissions to a group of users simultaneously. Since the data transmitted to each user are different, in order to ...

Multi-User Diversity vs. Accurate Channel Feedback for MIMO Broadcast Channels
— A multiple transmit antenna, single receive antenna (per receiver) downlink channel with limited channel feedback is considered. Given a constraint on the total system-wide cha...

Effects of Non-Ideal Channel Feedback on Dual-Stream MIMO-OFDMA System Performance
— In this paper we analyze the downlink OFDMA system-level performances of a 2x2 dual-stream MIMO multiuser transmission scheme under the assumptions of partial and noisy channel...
