Fig. 11. The average probability of error with and without incorporating for the cases (a) αg = 0 and αb ∈ [0.1 : 0.1 : 1], and (b) αg ∈ [0.001 : 0.001 : 0.01] and αb = 100× αg is presented. The BCH[1024, 728, 62], RM-(4, 10) and RM-(5, 10) codes are being used. The BER comparison results are obtained using the equations (33) and (34), and executing the GBP-guided DBF algorithm over at least 50,000 random instances of user messages.
