Sum-Capacity of Massive MIMO Systems Using Vandermonde Matrices
2020
In this paper, we use a series expansion to calculate the sum-capacity of a massive Multiple-Input MultipleOutput (MIMO) system under propagation environment
described by a dominant line-of-sight. The sum-capacity is
written as Taylor’s series where each term is a function
of the mean trace of k-th power of the channel matrix
W. We analytically derive the mean trace of first, second,
third, and fourth moments of W. Although the series is
infinite, our numerical results show that only a few terms
can tightly approximate the exact sum capacity. Numerical
results corroborate our analytical expressions.
