Co-channel interference modeling for land mobile radio system

Every upcoming generation of wireless communication is based on the integration of different application. This integration needs increase in capacity or spectral efficiency, possible either by decreasing the fading effects or by spectral reuse. Various diversity combining technique has been proposed in literature to mitigate the fading effects. Either using diversity combining techniques or spectral reuse causes interference; moreover the spectral reuse is main reason for the co channel interference. So the Interference modeling has become a challenging research area for the performance analysis and improvement of wireless communication system. Closed form solution for co-channel interference for Rayleigh distribution of received signal have been given in the past. In this paper, we have verified the past model and given a simple analytical model for other important fading distribution like Weibull distribution and Nakagami distribution giving a closed form solution for co-channel interference assuming that the interferers are linearly located.
