RESUMO

In this dissertation, a theoretical and mathematical study about fading channels modeled according to the n- distribution is presented. The n- distribution includes the Hoyt and the Nakagami-m distributions as special cases, and therefore, the One-Sided Gaussian and the Rayleigh distributions also constitute special cases. This dissertation presents the evaluation of performance in terms of average error probability of the n- fading channel with and without the use of the diversity technique. It also presents graphicals of the average error probability versus SNR (Signal-to-Noise-Ratio) calculated from numerical methods of integration and compares then with the traditional curves of error probability.
