Webtypically assume either Rayleigh paths or independently, iden-tically distributed (i.i.d.) Nakagami or Rician paths. These idealizations are not always realistic since the average fad-ing power [21], [22] and the severity of fading [23]–[25] may vary from one path to the other when, for example, multipath diversity is employed.
