摘要：
In this paper, a new QoS-Guarantee resource allocation scheme is proposed for multi-user MIMO-OFDM systems. Based on channel state information (CSI), the base station (BS) employs singular value decomposition (SVD) to transmit the MIMO channel into parallel eigenmode subchannels for each subcarrier, and then subcarriers, bits and power are dynamically allocated to users according to user's support subcarrier rate, the queue status of traffics and user's quality of service (QoS) requirement. Moreover, subcarrier reallocation is executed in order to heighten user's transmission rate and improve the utilization of system's resources. Simulation results demonstrate the superior performance of our proposed scheme, which can not only guarantee user's QoS requirement, keep user fairness, but also can greatly improve the cell throughput.
