Bivariate η-μ Fading Distribution with Application to Analysis of Diversity Systems

In this letter, we derive expressions for the moment generating function (MGF), for the probability density and cumulative distribution functions, as well as for joint moments of the bivariate η-μ fading distribution. By using the MGF-based approach, we obtain a finite-integral expression for evaluation of the bit error probability in dual-branch diversity systems with correlated branches. We present also an algorithm for generation of two correlated η-μ variables.
