—This paper studies the problem of minimizing symbol loss probability while keeping the system throughput above a certain threshold in downlink transmission of future OFDMA based...
Abstract— In this paper, we consider the unclaimed subcarriers that no user feeds back in an opportunistic OFDMA system with a per sub-carrier power constraint. Unclaimed subcarr...
— This paper addresses advanced radio resource management (RRM) algorithms for multiple-input multipleoutput (MIMO) transmission schemes in downlink OFDMA systems. The analysis c...
In the OFDMA downlink, obtaining Channel State Information (CSI) from users is necessary for the Base Station (BS) to optimize network performance by intelligently allocating resou...
Opportunistic scheduling and beamforming schemes are proposed for multiuser MIMO-SDMA downlink systems with linear combining in this work. Signals received from all antennas of ea...
