In most cases, the interfering transmitters are not clear and hence, people study this kind of phenomenon. In this work we use a wireless fading channel where useful signal is subject to a-k-u multipath fading, and co- channel a-k-u multipath fading. The communication channel we used is addressed using a random process. Since the interference is significant wireless networks, the channel model ignores influence of receiver noise on the system performance. Finally, we analyse the influence of a-k-u multipath fading severity and nonlinearity parameters.
