Abstract: In this paper, we present the closed-form expressions of composite Nakagami-m/log-normal (NL) fading channel by Holtzman approximation. The obtained expressions are used to derive the important performance parameters of wireless communications systems. These performance matrices are amount of fading (AF), outage probability (PO), average channel capacity (CC) and average symbol error probability (ASEP) of coherent modulation comprising binary orthogonal, antipodal, M-ary phase shift keying (M-PSK) and M-ary pulse amplitude modulation (M-PAM). Furthermore, energy detection (ED) is one of the ways to determine whether the signal is present or not. The performance of ED is studied in terms of complementary receiver operating characteristics (CROC) curve. To verify the correctness of our analysis, the derived closed-form expressions are corroborated via exact result and Monte Carlo simulations.
