	Fading distribution
		In telecommunication, a fading distribution is the probability distribution that signal fading will exceed a given value relative to a specified reference level.
		In the case of phase interference fading, the time distribution of the instantaneous field strength usually approximates a Rayleigh distribution when several signal components of equal amplitude are present.
		The fading distribution may also be measured in terms of power level, where the unit of measure is usually watts per square meter and the expression is in dB.

	Trellis coded modulation for transmission over fading mobile satellite channel - Patent 4945549
		Fading, which for mobile satellite channels can be assumed to be modelled by a Rician distribution, not only introduces an error floor into the system but also makes the problem of carrier recovery more difficult.
		The faded noise-corrupted in-phase and quadrature signal components of the IF signal are: demodulated by a quadrature demodulator 21 aided by the pilot tone(s) from an extractor 22; q-bit quantized by a quantizer 23.sub.q for soft decision decoding; and then block deinterleaved by a deinterleaver 24.
		For mobile satellite communication, multipath fading produces a received signal with an amplitude which can be modelled by Rician statistics with parameter K representing the ratio of the power in the direct (line-of-sight) and specular component to that in the diffuse component.

	Fading Channel Model
		The purpose of this assignment is to investigate fading multipath channels with doppler using the Capsim simulation environment.
		The second topology is used to sweep the fading channel across a band of frequencies to investigate multi-path phenomena.
		Since the fading channel model is a low pass equivalent model, by inputting a complex sinusoid we are shifting the Carrier by that sinusoid.

		In the case of phase interference fading, the time distribution of the instantaneous field strength usually approximates a Rayleigh distribution when several signal components of equal amplitude are present.
		The fading distribution may also be measured in terms of power level, where the unit of measure is usually watts per Fading distribution square meter and the expression is in dB.

	Rician Fading
		Similar to the case of Rayleigh fading, the in-phase and quadrature phase component of the received signal are i.i.d.
		However, in Rician fading the mean value of (at least) one component is non-zero due to a deterministic strong wave.
		The derivation is similar to the derivation for Rayleigh fading.

	RAND \| Paul Baran: Distributed Communications - Mini-Cost Microwave - Required Signal/Noise Ratio (Site not responding. Last check: )
		The rationale is simple: Fading errors are highly clustered and exhibit the property that if a bit is received in error due to fading, adjacent bits have a high probability of also being in error.
		Figure 2 compares alternative estimates of microwave link fading and plots the depth of fade in decibels versus the fractional time the fade is in excess of the abscissa.
		If Rayleigh fading is assumed, then a span composed of ten tandem links is operative 97 per cent[9] of the time; with the Durkee or the French B.T.T. curves, the figure is 99.3 per cent.

	Overview of Spatial Channel Models for Antenna Array Communication Systems
		Based on the flat fading channel model developed by R. Clarke in 1968, Gans assumed that the received signal at the mobile station came from all directions and was uniformly distributed.
		This distribution is time-variant due to mobile motion and depends on the location, orientation, and velocity of the mobile station antenna and the topographical and morphographical properties of the propagation area as well.
		The distribution of the angle of arrival of the rays within a cluster presented a sharp peak at the mean, leading to the Laplacian distribution modeling.

		- Rayleigh Fading Distribution: The Rayleigh Fading Distribution is used to describe the statistical time varying nature of the received envelope of a flat fading signal, or the envelope of an individual multipath component.
		The Ricean distribution is often described in terms of a parameter K which is defined as the ratio between the deterministic signal power and the variance of the multipath.
		As A->0, K->-infinity dB, and as the dominant path decreases in amplitude, the Ricean distribution degenerates to a Rayleigh distribution.

	search Abstract
		Nakagami's (1960) fading model is widely adopted for analyzing wireless communication systems and diversity combining techniques, hence the ability to generate Nakagami fading signals with arbitrary parameters is important for system design and simulations.
		The correlated Nakagami fading variables are generated from the corresponding uncorrelated gamma random variables (RVs).
		To achieve this, we propose a new decomposition method, and introduce Sim's (1992)method as a complementary approach, to generate correlated gamma RVs.

		Step 3: Calculate the percentage of time p fade depth A is exceeded in the large fade depth tail of the distribution for the average year from: EMBED Equation.3 (25) Step 4: If the shallow fading range of the distribution is required, follow the method of § 2.3.2, replacing pw by p.
		The LAD approach estimates the distortion distribution on a given path that would be observed at two frequencies in the radio band and makes use of modulator and equalizer characteristics, etc. Similarly, the net-fade margin approach employs estimated statistical distributions of ray amplitudes as well as equipment information, much as in the LAD approach.
		A tradeoff must be made between the reduction of the effects of multipath fading and distortion and the increased fading due to sub-refraction.

	CNN - La Niña is on its way out - April 26, 1999
		The La Niña weather phenomenon that followed on the heels of the most powerful El Niño on record is beginning to fade, according analysis of the latest images from the U.S.-French TOPEX/Poseidon satellite.
		The imagery of sea-surface heights taken this month by the ocean-observing satellite show cooler temperatures and lower sea levels across the equatorial Pacific Ocean (seen in blue and purple in the center of the image) are diminishing, which indicates that the equatorial Pacific is slowly returning to normal.
		In a nutshell, this means that although La Niña is fading, heat distribution in the Pacific Ocean remains dramatically out of balance.

		Though less expensive, the painted lamps suffer from fading or flaking of the paint when exposed to weather.
		Rather than being dome-shaped (convex), the envelope is concave (sunken in) to cause wider distribution of light.
		For this reason, many Americans treat mini Christmas lights as being disposable, in addition to colored lights tending to fade even with only brief exposure to weathering.
