Query: Diversity-Multiplexing Tradeoff of Double Scattering MIMO Channels   It is well known that the presence of double scattering degrades the
performance of a MIMO channel, in terms of both the multiplexing gain and the
diversity gain. In this paper, a closed-form expression of the
diversity-multiplexing tradeoff (DMT) of double scattering MIMO channels is
obtained. It is shown that, for a channel with nT transmit antennas, nR receive
antennas and nS scatterers, the DMT only depends on the ordered version of the
triple (nT,nS,nR), for arbitrary nT, nS and nR. The condition under which the
double scattering channel has the same DMT as the single scattering channel is
also established.
