3diversity receivers in Weibull fading

A novel approach to the performance analysis of switched-and-stay combining diversity receivers over independent Weibull fading chan-nels is presented. Closed-form expressions are extracted for impor-tant performance parameters, such as the average output signal-to-noise ratio, the amount of fading, the outage probability, and the switching rate. Introduction: Among all well-known diversity techniques, switched-and-stay combining (SSC) is simpler and cheaper though less efficient. In a dual-branch SSC system, if the instantaneous signal-to-noise ratio (SNR) of the first branch falls below a predefined switching threshold, the second branch is immediately selected
