摘要：

In this paper, resource allocation problems for multiuser space-time block coding based OFDM systems are investigated. Specifically, with the goal of minimizing overall transmit power, a subcarrier, power assignment criterion and an recursive allocation algorithm which fulfills users' QoS requirements, including bit error rate and data rate constraint are proposed. Analyses and numeric simulations demonstrate that the proposed subcarrier assignment schemes can exploit multiuser diversity to provide significant system-level performance improvement and guarantee different users' QoS requirements effectively.
