LCR of the Ratio of the Product of Two Squared Nakagami-m Random Processes and Its Application to Wireless Communication Systems

The paper takes into account second order statistics (SOS) of the ratio of the product of two squared-Nakagami-m (s-N-m) random processes (RPs). The obtained results can find their application in variety of wireless communication systems (WCSs). Mathematical apparatus has been developed for deriving fast computing, closed form, approximative expression for level crossing rate (LCR) using Laplace integration formula. The influence of s-N-m fading severity parameters for the proposed RP on the LCR is investigated and graphically presented for radio frequency (RF) WCS as well as optical WCS (OWCS) scenarios.
