摘要：

With the development and applications of high-speed wireless communication techniques. Orthogonal Frequency Division Multiplexing (OFDM) techniques and Multiple Input and Multiple Output (MIMO) techniques have applied in broadband wireless communication system. Using robustness of OFDM technology to multi-path effects, MIMO technology can easily be applied to broadband wireless communications. We extend the synchronization algorithms for OFDM systems to MIMO-OFDM systems and. a synchronization algorithm for MIMO-OFDM systems is proposed. It has nice estimation performance and no pilots are needed. On the research of adaptive power and bits allocation scheme in MIMO-OFDM system, an adaptive resource allocation algorithm is proposed. This algorithm is simple and practical. The simulation results suggest that the algorithm has good performance.
