© 2015 IEEE. In this paper, in heterogeneous cellular networks (HCN), we first consider an approximation model for the aggregate adjacent channel interference (ACI) from nearby small-cells at a user in a macro-cell. With the help of two well known approximations for ACI, the signal to interference ratio (SIR) of users in a macro-cells (victim users) is derived in the presence of coexisting small-cells. In addition, the outage probabilities of the victim user in HCN is also derived to measure the performance of the system. Through simulations, we can demonstrate that as the small-cell intensity increases, the outage probability of victim user increases. Furthermore, under the same small-cell intensity, it is shown that as the distance between the user and its macro-cell base station (BS) increases, the outage probability also increases.
