| 摘 要： | 针对于多用户MIMO-OFDM下行传输,本文提出了一种基于用户信道特征,利用多天线选择和子载波组分配相结合的新型自适应算法.该算法在不明显降低系统整体性能的前提下可大大降低发射端计算复杂度,使之更适用于实时信道传输环境.仿真结果表明,该算法在计算复杂度大幅减小的情况下仍能保证系统性能无明显损失.

| Abstract: | In this paper, we propose a real-time adaptive subcarrier band allocation algorithm combined with antenna selection in multiuser MIMO-OFDM downlink transmission based on channel characteristic of users. This algorithm can significantly reduce the computing complexity of transmitter without apparent performance attenuation, which is more suitable for real-time environment. Simulation results showed that our proposed algorithm can obtain the approxi- mate optimal performance with significant computing complexity reduction. |
