Abstract

We derive new upper and lower bounds on the fading number of
non-coherent multiple-input single-output (MISO) fading channels of
general (not necessarily Gaussian) regular law with spatial and
temporal memory. The fading number is the second term, after the
double-logarithmic term, of the high signal-to-noise ratio (SNR)
expansion of channel capacity.

In case of an isotropically distributed fading vector it is proven
that the upper and lower bound coincide, i.e., the general MISO
fading number with memory is known precisely.

The upper and lower bounds show that a type of beam-forming is
asymptotically optimal.
