| 抄録（和） | In the conventional subcarrier and power allocation schemes in Multi-Input Multi-Output and Orthogonal Frequency Division Multiple Access (MIMO-OFDMA) systems, only equal fairness among users has been considered, and no scheme for proportional data rate fairness is considered. In this paper, subcarrier and power allocation criterion is proposed to maximize the total throughput under the constraints of total power and proportional data rate fairness among users. In the proposed scheme, subchannel allocation is firstly performed by using singular value decomposition (SVD) of channel matrix under the constraint of users data throughput requirements, and then adaptive bit and power loading is applied. Simulation results show that total throughput is increased as well as each throughput is proportionally distributed among users in MIMO-OFDMA systems. |
