this paper, we study the capacity limits of dense multiantenna

systems. We derive asymptotic capacity expressions

for point-to-point and broadcast channels by applying recent

tools from random matrix theory. In the case of broadcast

channels, we focus on linear precoding techniques. We found

that the asymptotic capacity depends only on the ratio between

the size of the antenna array and the wavelength.

This provides useful guidelines on the achievable limits of

information transfer. In particular, it is shown that the total

capacity grows unbounded if the transmitter has perfect

knowledge of the channel, while the capacity saturates in

the absence of channel knowledge at the transmitter. We

provide numerical results supporting the theoretical derivations.
