标题： Capacity Scaling Law in Massive MIMO with Antenna Selection

摘要： 天线选择能够解决大规模多输入多输出（MIMO）信道中的成本和复杂性问题。 在Nakagami衰落下表征了多用户大规模MIMO上行链路信道的总速率容量。 为所考虑的系统推导出了一个数学上易于处理的总速率容量上界。 此外，对于基站（BS）天线数量足够大的情况，推导出了总速率边界的一个确定性等效（DE）。 基于此DE，表明总速率容量随着基站天线数量以双对数增长。 通过数值实验验证了分析结果的有效性。 显示英文摘要

摘要： Antenna selection is capable of handling the cost and complexity issues in massive multiple-input multiple-output (MIMO) channels. The sum-rate capacity of a multiuser massive MIMO uplink channel is characterized under the Nakagami fading. A mathematically tractable sum-rate capacity upper bound is derived for the considered system. Moreover, for a sufficiently large base station (BS) antenna number, a deterministic equivalent (DE) of the sum-rate bound is derived. Based on this DE, the sum-rate capacity is shown to grow double logarithmically with the number of BS antennas. The validity of the analytical result is confirmed by numerical experiments.
