Adaptive Subcarrier Allocation for Multiuser MIMO OFDM Systems in Frequency Selective Fading Channel

摘要：

In this paper, the impact of multiuser diversity for V-BLAST based OFDM systems in frequency selective fading channel is considered, and a multiuser subcarrier allocation criterion is developed aimed to optimizing the system-level performance. Mathematical analyses and numeric simulations demonstrate that the proposed subcarrier assignment strategy outperforms the static assignment scheme significantly, even with little amount of feedback. In order to guarantee the users quality of service (QoS), a reallocation algorithm is given, and it behaves well in our experiments.
