The Diversity-Multiplexing Tradeoff (DMT) in shadowed Nakagami fading channels is evaluated while the multiple antennas technique is used at the transmit or receive sides. We show that at the infinite Signal to Noise Ratio (SNR), the asymptotic DMT is not affected by the lognormal shadowing. However, the shadowing phenomena can dramatically reduce the achieved finite SNR diversity gain for all multiplexing gains. Also, we derive the effect of the Nakagami fading parameter on the provided DMT by MISO/SIMO channels and show that the diversity gain is directly influenced by this parameter.
