RESUMO

This work provides the following contributions to the study of fading channels: (i) closed-form approximations to the probability density function and the cumulative distribution function of sums of independent envelopes under Nakagami, Rice, Hoyt, Weibull, or lognormal fading; (ii) general expressions for the average fade rate and the average fade duration of pure selection combining over arbitrary fading channels; (iii) general expressions for the average fade rate and the average fade duration of pure selection, equal-gain, and maximal-ratio combining over correlated Ricean channels, and (iv) envelope simulator for Nakagami fading channels, applicable to arbitrary values of fading parameter and nonisotropic propagation scenarios
