  We study analogue source transmission over MIMO block-fading channels with
receiver-only channel state information. Unlike previous work which considers
the end-to-end expected distortion as a figure of merit, we study the
distortion outage probability. We first consider the well known transmitter
informed bound, which yields a benchmark lower bound to the distortion outage
probability of any coding scheme. We next compare the results with
source-channel separation. The key difference from the expected distortion
approach is that if the channel code rate is chosen appropriately,
source-channel separation can not only achieve the same diversity exponent, but
also the same distortion outage probability as the transmitter informed lower
bound.
