Abstract

A novel distribution referred to as N*generalized κ, constructed as the product of N statistically independent, but not necessarily identically distributed, generalized κ random variables (RVs) is introduced. Statistical characterization of the proposed distribution is carried out via the derivation of closed-form expressions for its moment generating, probability density, cumulative distribution and moment functions. Using the obtained formulas, we present new closed-form expressions for the outage probability, the bit error probability and the average channel capacity of a digital communication system operating over the N cascaded generalized κ distributed channels.
