  The effective rate of Fluctuating Beckmann (FB) fading channel is analysed.
The moment generating function (MGF) of the instantaneous signal-to-noise (SNR)
is used first to derive the effective rate for arbitrary values of the fading
parameters in terms of the extended generalised bivariate Meijer's-$G$ function
(EGBMGF). For integer valued of the multipath and shadowing severity fading
parameters, the probability density function (PDF) of the instantaneous SNR is
employed. To this end, simple exact mathematically tractable analytic
expression is obtained. The Monte Carlo simulations and the numerical results
are presented to verify the validation of our analysis.
