Abstract
In this letter, we derive exact expressions for the probability density function, the cumulative distribution function, and the {n} -th moment of the maximum of {L} independent and not necessarily identically distributed (i.n.i.d.) extended \eta - \mu variates. The derived statistics are obtained in closed-form in terms of multivariate I-function. Capitalizing on these results, the performance of {L} selection combining diversity receiver is studied by means of outage probability (OP), average symbol error rate (SER), and ergodic capacity. Besides, simple closed-form asymptotic expressions, in terms of elementary functions, for the OP and average SER are obtained. Monte-Carlo simulation results are provided to verify the new analytical results.
