Switching rates of dual selection diversity in κ-μ and α-μ fading channels

Switching rate is an important parameter in selection diversity receiver design because the switching transients increase the system outage. An exact closed-form solution for the switching rate of dual selection diversity in κ-µ and α-µ distributed fadings is derived. Independent and identically distributed (i.i.d.) κ-µ and α-µ fading channels are considered. The switching rate for dual i.i.d. κ-µ distributed fading includes the switching rate for dual i.i.d. Rayleigh, Rician and Nakagami-m fading channels as special cases. Similarly, the switching rate for dual α-µ fading channels also includes special cases such as Rayleigh, Nakagami-m and Weibull fading channels.
