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.

To achieve the goal of favorable trade-off between performance in severe multipath fading channel and complexity of signal processing, the single-carrier frequency-domain equalization (SC-FDE) has recently attracted increased interest because of its similar performance, efficiency, and low signal processing complexity advantages as OFDM, and in addition it is less sensitive than OFDM to radio frequency (RF) impairments such as power amplifier nonlinearities.
