We must take heed to the point that the combined estimates that are received estimations from neighboring nodes are affected by channel noise and fading coefficients, through the links.
The CTA algorithm formulation with the presence of the channel fading and noise is then given as:
2.2 Adapt Then Combine (ATC) diffusion strategy with noisy and fading links
ABER values are obtained capitalizing on conditional SER relations, which are conditioned over fading statistics which impairs the communication.
For the first time, characterization has been provided for equivalent SIR random process, which arises in wireless communication channel due to effects of kappa-mu shadowed fading and multiple Rayleigh CCIs, by deriving closed-form expressions for standard first order statistic measures, PDF and CDF.

In the high SNR regime, the effects of small and large-scale fading on the ergodic capacity are decoupled.
It is demonstrated that the effect of small-scale fading is canceled and the sum rate is affected by the large-scale shadowing fading and path loss.
The remainder of the paper is organized as follows: In Section 2, we introduce the D-MMO fading model and provide the definition of ergodic capacity.
The phenomenon of signal fading can be described evaluating an impact of many atmospheric parameters.
After estimation of annual fading distributions in these links, different and mixed atmospheric parameters in corresponding terrains were analysed empirically.
In reality it is very difficult to distinguish when the signal fading originates because of the rain or multipath propagation or some other conditions.
