Application of Gaussian Q-Function Approximations in Fluctuating Beckmann Fading Model

This letter is an application of various exponential-based approximations to Gaussian Q -function, which are used to derive a generalized closed-form solution for the symbol error probability (SEP) over recently introduced Fluctuating Beckmann fading model. This model covers all the other important fadings like Gaussian, Rayleigh, Rician, Nakagami- m , η - μ , κ - μ , shadowed Rician and κ - μ distributions as special cases. The SEP expression is mathematically effortless and requires elementary power function computations only.
