Abstract: This paper presents a novel frequency reuse scheme that reduces the effects of co-channel interference and in-creases the capacity of orthogonal frequency division multiplexing (OFDM) systems. To increase the capacity of a system, the frequency reuse factor should be close to 1. In general, reduction of co-channel interference (CCI) is achieved at the cost of cell capacity. Our virtual frequency reuse (VFR) targets to mitigate such tradeoff. In VFR, the type of a cell is determined by the order of sub-channel assignment. And users in a cell are assigned sub-carriers among sub-channels by a specific regulation. Probabilistic interference analysis and simulation results show that the proposed virtual frequency reuse improves the performance of an OFDM system for both uniform and non-uniform distributions of traffic load.
