| 摘 要： | 针对多用户总速率和最大化算法,很少考虑用户之间公平性的不足,提出一种多用户功率优化算法,在满足每个用户速率要求的前提下,使多用户MIMO-OFDM系统的发射功率最小.仿真结果表明,该算法可在10-6>的精度内满足不同用户速率要求,同时所需的下行系统发射功率与理论上最少的基于循环迭代注水算法的DPC传输方式接近,具有较高的实用价值. |

| Abstract: | By considering the shortage of multi-user sum-rate maximization algorithm which is lack of fairness among users,a new optimal multi-user power scheduling algorithm is proposed.The proposed algorithm minimizes the transmit power of multi-user MIMO-OFDM system while meet each user' s rate requirement.Simulation results show that the proposed algorithm can meet each user' s rate requirement in 10-6 precision.And the required transmit power of proposed algorithm approximates to that of iterative water-filling b... |
