The Second Order Scattering Fading Model With Fluctuating Line-of-Sight López-Fernández, Jesús Anaya López, Gonzalo Javier López Martínez, Francisco Javier Channel modeling fading models Rice We present a generalization of the notoriously unwieldy second order scattering fading model, which is helpful to alleviate its mathematical complexity while providing an additional degree of freedom. This is accomplished by allowing its dominant specular component associated to line-of-sight propagation to randomly fluctuate. The statistical characterization of the newly proposed model is carried out, providing closed-form expressions for its probability and cumulative distribution functions, as well as for its generalized Laplace-domain statistics and raw moments. We exemplify how performance analysis can be done in this scenario, and discuss the role of the fading model parameters on system performance. 2024-10-07T12:14:45Z 2024-10-07T12:14:45Z 2024-09 journal article López Fernández, J. & Anaya López, G.J. & López Martínez, F.J.
