  In this paper we introduce a novel performance analysis of the
${\eta}$-${\mu}$ generalized radio fading channels with integer value of the
${\mu}$ fading parameter, i.e. with even number of multipath clusters. This
fading model includes other fading models as special cases such as the
Nakagami-m, the Hoyt, and the Rayleigh. We obtain novel unified and generic
simple closed-form expressions for the average bit error rates and ergodic
channel capacity in the additive white generalized Gaussian noise (AWGGN),
which includes the additive Gaussian, the gamma, the Laplacian, and the
impulsive noise as special cases. The receiver is assumed to be an L-branch
maximal ratio combiner where we study the effect of having more deployed
receiver antenna. Numerical evaluation as well as results from technical
wireless literature validate the generality and the accuracy of the derived
unified expressions under the studied test cases.
