MGF‐based analysis of κ‐μ/gamma composite fading model for indoor off body communication

다국어 초록 (Multilingual Abstract)

This paper presents the moment generating function (MGF)–based analysis of κ‐μ/gamma composite fading model, which is suitable for the indoor off‐body communication channel. In this paper, first of all, we derive an analytical expression for MGF of instantaneous signal‐to‐noise ratio. By using the derived MGF, the expressions of average symbol error rate (ASER)/average bit error rate (ABER) for binary and M‐ary modulation scheme are derived. Using the MGF approach, we also derive the expression of channel capacity for optimum rate adaption and channel inversion with fixed rate policy. The derived expressions for ABER/ASER and channel capacity are presented in the infinite series form. We further present the numerical results of error rate and channel capacity for different values of κ, μ, α, and β parameters. The result of ABER and channel capacity shows good agreement with the previously reported results as special cases that verify the derived expressions.







This paper presents the moment generating function (MGF) based analysis of κ‐μ/gamma composite fading model for indoor off‐body communication channels. In this paper, an analytical expression for MGF of instantaneous SNR has been derived. By using this derived MGF, the expressions of ASER)/ABER for binary and M‐ary modulation scheme are also derived. Further, by using MGF approach the expression of channel capacity for ORA and CIFR policy have also been derived explicitly.
