Abstract-- Limits of information transfer over a discrete time
uncorrelated Rayleigh fading MIMO channel is considered,
where neither the transmitter nor the receiver has the knowledge
of the channel state information (CSI) except the fading statistics.
We show the capacity supremum with the receive antenna
number at any SNR using Lagrange optimisation. Furthermore,
we show the asymptotic capacity when the input power is large,
and compare with the existing capacity results when the receiver
is equipped with large number of antennas.
Index Terms-- Channel capacity, mutual information, Rayleigh
fading, upper bound, SISO, MIMO, Lagrange optimisation.
