Optimal Downlink OFDMA Resource Allocation with Linear Complexity to Maximize Ergodic Rates
OFDMA resource allocation assigns subcarriers and power, and possibly data rates, to each user. Previous research efforts to optimize OFDMA resource allocation with respect to comm...

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 ...

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 ...
