Abstract
This paper considers theoretical link spectral efficiency limits of
multi-antenna channels with composite Rayleigh multipath fading and
log-normal shadowing. The relevant limits include e-achievable and
delay-limited link spectral efficiencies which are defined with respect to
the availability of the channel state information at the transmitter and the
receiver. The numerical results suggest that the shadowing seriously limits
the achievable link spectral efficiencies. The difference between e-achievable
link spectral efficiencies in non-shadowed and shadowed channels is
approximately linearly proportional to the minimum number of antennas.
Furthermore, the availability of the channel state information at the
transmitter, in addition to the receiver, significantly increases the
e-achievable link spectral efficiency in shadowed channels. In non-shadowed
channels the respective increase of the e-achievable link spectral efficiency
is less pronounced.
