我们考虑发射机优化问题,以最大化多天线蜂窝系统的下行链路总速率,其中基站之间具有完美的数据协作以及每个基站单独的功率约束。为了执行这种非凸下行链路发射机优化,我们研究了与 BC-MAC 对偶结果相结合的增量功率分配策略。
We consider the problem of transmitter optimization to maximize the downlink sum rate of a multiple antenna cellular system with perfect data cooperation between the base stations and a separate power constraint per base station. To perform this non-convex downlink transmitter optimization we investigate incremental power allocation strategies combined with BC-MAC duality results.
