fading skin coloring. See Arabian fading syndrome (below). Declining in body condition, general health, activity and productivity.

Arabian fading syndrome
general health is unimpaired. Affected horses, usually Arabians, gradually lose their skin coloring on round, depigmented macules and multiple patches, most obviously around the muzzle and the perineum. It is a noninflammatory leukoderma. The cause is unknown. See also vitiligo. Called also pinky syndrome, lavender foal.

fading kitten/puppy syndrome
apparently normal young are born, but within the first week or two of life individuals within the litter gradually weaken and die. Not a specific disorder, but generally applied to infectious causes.

Theorem 2: For non-correlated K fading D-MIMO channels, the lower bound of the ergodic capacity for D-MIMO systems is
Comparing Proposition 1 and Proposition 3, we can conclude that the two propositions have the similar conclusion except the small-scale fading.
From the result of (35), we can observe that the effects of small-scale fading can be omitted for the number of the BS antennas grows without bound.
It is assumed that the shadow fading parameters are fixed constant, i.
Proof: Using the shadow fading parameter assumption, the lower bound of corollary 6 can be further simplified as
We reap the multipath and shadowing fading matrix H and [THETA] according (2) and (4) by generating 100000 random realizations and thereafter get the simulated ergodic capacity via (5).
For illustration purposes, we assume that the large scale fading matrix is set to the identity matrix [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII].
In this paper, we elaborate on the ergodic capacity of D-MIMO systems over spatially non-correlated K fading channels.
