Abstract :
This paper addresses investigations and modeling of inter-cell interference of a next generation cellular orthogonal frequency division multiplexing access (OFDMA) transmission system on the link-level. Different strategies, i.e., Gaussian approximation (GA) and binomial method, for modeling the intercell interference are given and investigated. Furthermore, the influence of the closest interfering cells and time synchronization offsets are in the focus. Concluding from the investigations, the GA for the inter-cell interference is an appropriate modeling in the case of single antenna systems and linear receivers
