| 摘 要： | 针对多输入多输出（MIMO）-正交频分复用（OFDM）系统，提出了功率控制与波束赋形的联合优化算法，采用更加符合实际系统的干扰模型，将节能问题建模为功率控制与波束赋形的联合优化问题.为了求解上述非凸问题，基于上下行对偶原理和标准干扰函数理论，提出一种两阶段解决方案，并给出相应的理论证明该方案的收敛性.仿真结果表明，所提算法在多天线场景下相对于现有算法有更快的收敛速率，与传统的波束赋形方案相比，具有更低的能耗. |

| Abstract: | A joint optimization problem of power control and beamforming for multiple input multiple output (MIMO)-orthogonal frequency division multiplexing (OFDM) system with more realistic interference model was proposed. Then a two-stage scheme based on dual of uplink-downlink and standard interference mapping theory was given to solve this problem, which is proved to be rigorously convergent. Simulations show that the proposed scheme converges faster in multiple-antenna cases and the proposed algorithm outperforms the traditional ones in terms of power saving. |
| Keywords: | multiple input multiple output-orthogonal frequency division multiplexing system power control beamforming |
