摘      要：Channel hardening characterises the diminishing influence of small scale fading on large scale antenna systems. The effective massive MIMO time domain channel is introduced and applied to a maximum diversity channel with rectangular power delay profile. This model bounds channel hardening and allows a proper interpretation from a radio design perspective. The reduced variability of the effective channel enables power inversion to obtain a downlink channel that only depends on the large scale fading properties. Copyright © 2019, The Authors.
