With the growing demand for wireless communication services at high transmission rates, perfect knowledge of channel statistics is of paramount importance. This Post doctoral Research Project aims to characterize the statistics of composite fading channels generated from: 1) the product of multiple envelopes; 2) the ratio of the product of multiple envelopes; 3) the sum of multiple envelopes. In all cases the fading variables will be taken arbitrarily from the fading models alpha-mu, eta-mu and kappa-mu. Several applications in communication systems use the processes mentioned in their analysis. Examples include multi-hop communication, multiple input and multiple output systems, physical layer security, equal gain combining, maximum ratio combining, and so on. The great relevance of the distributions of these composite channels demands a more precise and accurate characterization of their statistics. The alpha-mu, eta-mu and kappa-mu distributions are generic models that encompass more traditional ones such as Rayleigh, Hoyt, Rice, Weibull, and Nakagami-m, in such a way that a statistical characterization of the varied range of composite fading channels. In addition to the proposed themes, it is also desired to obtain fundamental results that deepen the knowledge and facilitate the practical application of the alpha-eta-kappa-mu model. It should be noted that the envelope of the alpha-eta-kappa-mu model can be understood as a suitable combination of the power of two arbitrary kappa-mu powers, that is, it can also be understood as a composite fading channel.In order to validate in practice the theoretical results to be obtained in this Project, an interaction is sought through an on-site internship with the Center for Wireless Innovation, Queen's University Belfast, one of the largest research centers in the United Kingdom, focused on physical layer of wireless communications systems. In fact, this interaction occurred throughout the candidate's PhD time, at which time several successful joint workings were developed.
