IEEE Transactions on Information Theory. See for a preprint.
This paper investigates the maximal achievable rate for a given
blocklength and error probability over quasi-static multiple-input
multiple-output (MIMO) fading channels, with and without channel state
information (CSI) at the transmitter and/or the receiver. The principal
finding is that outage capacity, despite being an asymptotic quantity,
is a sharp proxy for the finite-blocklength fundamental limits of
slow-fading channels. Specifically, the channel dispersion is shown to
be zero regardless of whether the fading realizations are available at
both transmitter and receiver, at only one of them, or at neither of
them. These results follow from analytically tractable converse and
achievability bounds. Numerical evaluation of these bounds verifies that
zero dispersion may indeed imply fast convergence to the outage capacity
as the blocklength increases. In the example of a particular 1×2
single-input multiple-output (SIMO) Rician fading channel, the
blocklength required to achieve 90% of capacity is about an order of
magnitude smaller compared to the blocklength required for an AWGN
channel with the same capacity. For this specific scenario, the
coding/decoding schemes adopted in the LTE-Advanced standard are
benchmarked against the finite-blocklength achievability and converse
