Abstract

This study investigated an existing cellular wireless communication system and found that the system performance was severely limited by co-channel interferences (CCI) within the cell and from users of other cells. Therefore, in addition to simulating the shadow fading and path loss models caused by the attenuation of wide-range signals and the Rayleigh fading caused by the attenuation of short-range signals required for general channel exploration, a co-channel interference model was also constructed. Finally, a structured simulation method is presented in the Conclusion section.
