Abstract
A new compound non-symmetric distribution for modeling arbitrary fading-shadowing wireless channels is introduced and studied here. This distribution has some advantages in front of other well-known non-symmetric fading distributions such as the Rayleigh–lognormal distribution and the K distribution especially in the tails. We give closed-form expressions for the average BER of DPSK and MSK when the new distribution is used. Applications to compare how the new distribution works in comparisons with the Rayleigh–lognormal, K distributions and others recently proposed in the literature of fading channel are also provided.

Speaking, fading refers to the interference of multiple scattered radio paths between the base station and the vicinity of the mobile receptor. This definition is enhanced to account for the new device-to-device communication systems, in this case, new constraints hold

Summary
Systems of mobile communications rising to the challenge of the 5G framework demand high data rates at a low latency [1,2]. The case of blocked line of sight between the stationary source (emitter) and the mobile receptor is shown In this case, the diffuse component shows a similar behavior than before (and it can be modeled by a Rayleigh distribution based on the assumption of a sufficiently large number of received waves at mobile terminal), but a new component appears: the shadowed direct component. The diffuse component shows a similar behavior than before (and it can be modeled by a Rayleigh distribution based on the assumption of a sufficiently large number of received waves at mobile terminal), but a new component appears: the shadowed direct component This component is due to the scattering of the signal by branches, leaves, and limbs of nearby trees and surrounded vegetation in general.
