Abstract

Dynamic resource allocation (DRA) in MIMO- OFDMA systems supporting multiple services is studied. A low complexity linear algorithm based on solving an RA optimization problem subject to an additional proportional fairness constraint is developed. Computer simulation results demonstrate that the proposed algorithm performs well, and the proportionality of rate among the users approaches the proportional rate constraint as the increasing of the available subcarriers. Furthermore, it has a lower computational complexity.
