Fading and Propagation Attenuation Based Explicit Analytical Model for the Pdf of Mobile Channel Composite Envelope

In this paper, we extend the explicit analytical expression for the probability density function of a mobile channel signal composite envelope, during simultaneous fast Nakagami and slow (shadowing) fading. This enables analytically explicit assessment of the mobile channel transmission quality of service, in contrast to currently actual solving similar problems exclusively through numerical integration methods and time-consuming simulations. Analytical results are extensively graphically represented for characteristic parameter values of fast and slow fading
