报告摘要：

It is well known that the massive multiple-input multiple-output (massive MIMO) system has potential to boost the channel’s beamforming gain that is also called as array gain or power gain. Specifically, the capacity of a massive MIMO channel may increase logarithmically with the number of antennas, which implies that infinitely massive antennas may achieve an infinite capacity, even with a finite power constraint at the transmitter. However, the above exciting result is based on a key assumption that the instantaneous fading coefficients are perfectly known to the receiver/transmitter (perfect CSIR/CSIT). In general, CSIR and CSIT entail channel training and feedback, and the overhead associated with training and feedback may in turn affect the channel capacity. Therefore, it remains open if a massive MIMO system could still provide a significant capacity benefit as we expected. In this talk, we will answer the following question: Can infinitely massive antennas always achieve an infinite capacity in a massive MIMO channel?
