If the obstacles are still between the transmitter and receiver, why would the fade last only up to minutes, instead of forever until the obstacles are gone?
WebSmall-scale fading superimposed on large-scale fading can be readily identified. The typical antenna displacement between the small-scale signal nulls is approximately a half … WebWe consider that the received signal-to-interference power ratio (SIR) at each hop is affected by large-scale fading (path-loss and shadowing) as well as small-scale Rayleigh fading. Assuming that the multiple CCIs in each hop are distributed as a Poisson point process on the infinite plane, we investigate the outage performance of the AF and ...
