In this work, the ratio of product of two Nakagami-m random processes and Nakagami-m random process (RP) is analyzed. Statistical characteristics of ratio of product of two RPs and RP is applied in performance analysis of relay communication systems with two sections operating in multipath fading channel in the presence of co-channel interference. Here, multipath fading is with Nakagami-m distribution, and cochannel interference is exposed to the influence of Nakagami-m small scale fading. Level crossing rate (LCR) of defined ratio is obtained using some useful mathematical manipulations and formulas. The influence of fading parameters and signal powers on the LCR is assessed based on some plotted graphs. By selection of the channel parameters, the system performance could be improved and higher reliability of wireless links achieved, what is important for command information systems.
