| 摘 要： | 针对单小区功率约束，本文考虑多天线多小区下行链路波束成形优化问题。在无法获得瞬时信道信息的条件下，本文基于信道二阶统计量，建立了单小区功率约束下的多小区上下行链路对偶性，并基于该对偶性，为单小区功率约束下行波束成形问题提出有效数值算法。

| Abstract: | This paper investigates transmit beamforming optimization problem with per-cell power constraints for multi-cell downlink systems. A uplink-downlink duality under per-cell power constraints is established, based on the second-order statistics of the channel coefficients instead of instantaneous channel state information. And with the aid of this duality, a effective algorithm is proposed for the beamforming problem with per-cell power constraints. |
