  We derive new upper and lower bounds on the fading number of 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.
