|  | p.d.f. of γ =| h [ m ]| 2 | Parameters |
|---|---|---|
Rayleigh model | \(\displaystyle \frac {1}{\bar {\gamma }} \exp \left (- \frac {\gamma }{\bar {\gamma }} \right) \) | \(\bar {\gamma }\) |
Rice model | \(\displaystyle \frac {(1+K)e^{-K}}{\bar {\gamma }}\exp \left (-\frac {\gamma (1+K)}{\bar {\gamma }}\right)I_{0}\left (2 \sqrt {K(K+1)\frac {\gamma }{\bar {\gamma }}} \right)\) | \(K,\bar {\gamma }\) |
Nakagami model | \(\displaystyle \frac {m^{m} \gamma ^{m - 1}}{\left (\bar {\gamma } \right)^{m} \Gamma (m)} \exp \left (-\cfrac {m \gamma }{\bar {\gamma }} \right) \) | \(m, \bar {\gamma }\) |
