Query: Large-System Analysis of Massive MIMO with Optimal M-MMSE Processing   We consider the uplink of a Massive MIMO network with $L$ cells, each
comprising a BS with $M$ antennas and $K$ single-antenna user equipments.
Recently, [1] studied the asymptotic spectral efficiency of such networks with
optimal multicell minimum mean-squared error (M-MMSE) processing when $M\to
\infty$ and $K$ is kept fixed. Remarkably, [1] proved that, for practical
channels with spatial correlation, the spectral efficiency grows unboundedly,
even with pilot contamination. In this paper, we extend the analysis from [1]
to the alternative regime in which $M,K\to \infty$ with a given ratio. Tools
from random matrix theory are used to compute low-complexity approximations
which are proved to be asymptotically tight, but accurate for realistic system
dimensions, as shown by simulations.
