BER curves for the asymptotic approximation, lower bound, and upper bound for MRC, SC, and EGC, over correlated BX fading channels. The number of branches is N = 2, the fading parameter is m = 1.5, and the correlation structure is Cb=[C1,02×2,02×2;02×2,C2,02×2;02×2,02×2,C3], where \({\mathbf {C}_{1}} = {\mathbf {C}_{2}} = {\mathbf {C}_{3}} = \left [ {1,\sqrt {0.4} ;\sqrt {0.4},1} \right ]\)
