This paper investigates the asymptotic uniform power allocation capacity of frequency nonselective multiple-input
multiple-output channels with fading correlation at either the
transmitter or the receiver. We consider the asymptotic situation,
where the number of inputs and outputs increase without bound
at the same rate. A simple uniparametric model for the fading
correlation function is proposed and the asymptotic capacity per
antenna is derived in closed form. Although the proposed correlation
model is introduced only for mathematical convenience, it
is shown that its shape is very close to an exponentially decaying
correlation function. The asymptotic expression obtained provides
a simple and yet useful way of relating the actual fading
correlation to the asymptotic capacity per antenna from a purely
analytical point of view. For example, the asymptotic expressions
indicate that fading correlation is more harmful when arising at
the side with less antennas. Moreover, fading correlation does not
influence the rate of growth of the asymptotic capacity per receive
antenna with high Eb /N0.Peer Reviewe
