Sistemas de Antenas Fluidas sob Desvanecimento Weibull e Diferentes Modelos de Correlação

In this article, the performance of fluid antenna systems (FAS's) is investigated by means of the outage probability (OP) considering different correlation models between the FAS ports and the channel subject to Weibull fading. To this end, new expressions for the probability density function and cumulative distribution function of N correlated Weibull random variables are derived. OP curves are plotted as a function of the number of ports under different parameter values that characterize the system and the channel. As a benchmark, the Rayleigh fading is also analyzed.
