Avaliação de técnicas para transmissão digital em canal com desvanecimento lento e não seletivo em frequência modelado com a distribuição n-µ

Abstract

In this dissertation a theoretical and mathematical study of channels modeled according to the n-μ distribution is presented. Such distribution encompasses the Hoyt and Nakagami-m distributions as special cases. Consequently, the Rayleigh and Semi-Gaussian Positive distributions are also obtained as special cases. The performance evaluation in terms of average error probability of the n-μ fading channel, with and without the use of diversity technique, is presented. Graphs of the mean error probability are presented by the SNR relation (signal-to-noise ratio), calculated from numerical integration methods. These graphs are compared to the traditional error probability curves.
