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 = 3, the fading parameter is m = 1.5, and the correlation structure is C_b=[C₁,0_3×3,0_3×3;0_3×3,C₂,0_3×3;0_3×3,0_3×3,C₃], where \({\mathbf {C}_{1}} = {\mathbf {C}_{2}} = {\mathbf {C}_{3}} = \left [ {1,\sqrt {0.4},\sqrt {0.2} ;\sqrt {0.4},1,\sqrt {0.4} ;\sqrt {0.2},\sqrt {0.4},1} \right ]\)
