“…In fact, in wireless networks, the RF signals are adversely affected by shadowing caused by the user's body [35]. Therefore, a composite fading model that includes multipath fading and shadowing scenarios [43] Nakagami-m Nakagami-m GG AF, fixed gain OP [20] η-µ Rayleigh α-µ AF, fixed gain OP, BER, EC [21] Nakagami-m Nakagami-m Double GG AF, fixed gain, variable gain OP, BER [2] Nakagami-m Nakagami-m Double GG AF, variable gain OP, BER, EC [44] Rayleigh Nakagami-m α-µ AF, fixed gain OP, BER, EC [45] Rayleigh Rayleigh M DF OP, BER, EC [46] Nakagami-m Nakagami-m M DF OP, EC This work κ-µ shadowed κ-µ shadowed Fisher-Snedecor F AF, fixed gain, variable gain OP, BER, EC simultaneously is necessary to be studied. The κ-µ [10], ηµ [10], α-η-κ-µ [36]- [38], and Rician shadowed distributions [39] are used to describe the above scenarios.…”
