From Fig. 7, we can see this approximation matches the empirical SINR very well.
We show that approximation matches the exact results remarkably well for outage probability, i.e., CDF, above 10%.
We characterize the possible outage values where the Gaussian approximation matches the exact results extremely well.
It is also worth to note that the Gaussian approximation matches with the simulation results quite well for the block.
As can be seen from these figures, the LN approximation matches quite well with the simulation results, though the proposed approximations work slightly better with lower fading variance (m = 16).
It is also shown that the closed-form approximation matches the simulation results very well, which verifies the accuracy of the approximation solution (29). Figure 9 Comparison of ergodic capacity of CSI-assisted and fixed gain relaying systems.
An EP update of the current approximation Q focuses on a site j ∈ {1,..., N}, constructing the distribution P ^ j (a ) ∝ Q(a ) t j (a j )/ t ˜ j (a j ), then adjusting b j, π j such that the new approximation Q' matches first and second order moments (mean and covariance) of P ^ j.
In each case depicted in Figure 3, the log-normal approximation matches the exact curve closely for probabilities between 0.1 and 0.9 but deviates considerably from the true value in the lower tail.
A separate asymptotic approximation matches the long-time sustained contact behavior for higher S, independent of the intervening number of separations.
The number of separations can be large over a small range of S. A semi-analytical approximation matches well the smaller-S behavior until first separation.
We observe that gaussian approximation matches better and better when the number of mobiles increases.
