This letter proposes a new model for the aggregate adjacent channel interference (ACI) received from nearby terminal stations (TSs) of heterogeneous wireless networks. It is well known that lognormal distribution approximates the aggregate received signal, but we found that it does not perform well for ACI-modeling among coexisting TSs. We propose a weighted sum of lognormals-based approximation (WSLA)...
Recently, as a variety of cellular systems are coexisted and the use of mobiles in a confined space increases, interference problems between terminals become more important. In this paper, we derive the closed-form probability density function (PDF) of the downlink signal-to-interference ratio (SIR) due to uplink transmission of the adjacent terminal station of the other system for the coexistence...
