    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.
