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.

Remark 1: It is easy to see that the lower bound of the sum rate monotonically grows with the mean of the LN shadow fading, and 3D antenna gain.
More importantly, these analytical results encompass the small- and large-scale fading (include LN shadow fading, 3D antenna gain and path-loss) models of practical interest.
In this simulation, we assume that all CUs suffer independent and identically distribution Rayleigh/Log-normal shadow fading channel with mean SNRs of PU signal at CUs are -16, -14, -12, -10 and -8 dB, respectively, and 6 dB of standard deviation.
Under both Rayleigh fading and Log-normal shadow fading conditions, the sensing performance of the proposed scheme and the OSC scheme are almost similar to the one of the EGC based scheme.
