... analysis of the capacity of N∗Nakagami-m channels. Specifically, we have studied the influence of the severity of fading and the number of hops on the PDF, CDF, LCR, and ADF of the channel capacity. ... the expressions for the statistical properties of the channel capacity C(t). Again, by applying the concept of transformation of random variables...
