Comments on “Human Body Shadowing in Cellular Device-to-Device Communications: Channel Modeling Using the Shadowed κ−μ Fading Model”
Moreno-Pozas, Laureano; López-Martínez, Francisco Javier; Cotton, Simon L.; París-Ángel, José Francisco; Martos-Naya, Eduardo (Institute of Electrical and Electronics Engineers, 2017-02)
We provide some comments and subsequent corrections to a paper recently published in this Journal (see ibid., vol. 33, no. 1, pp. 111-119, Jan. 2015). More precisely, we show that the pdf for the κ-μ shadowed fading model ... -
Eficiencia y control de potencia en canales de comunicaciones acústicas subacuáticas
