Switching Rates of Selection Diversity and Switch-And-Stay Diversity

The switching rates of dual-branch selection combining diversity and switch-and-stay combining diversity in Rayleigh, Rician and Nakagami-m (m half-integer or integer) fading are derived. The switching rate of selection combining is compared to that of switch-and-stay combining for the cases of balanced channels and unbalanced channels. The closed-form solutions have an explicit dependence on the Doppler frequency of the fading.
