An analytical model for reverse link outage probability in OFDMA wireless system

In a cellular OFDMA network, the outage probability is an important performance measure. It is useful in the design of a network to guarantee a certain quality of service (QOS) such as threshold Signal to interference ratio or data rate or bit error rate. In this work, a model is presented to determine the inter-cell interference (ICI) in downlink for a universal frequency reuse cellular OFDMA network. It is used to find the outage probability of a user for a given threshold SIR or Data rate or a target BER. From this the number of subcarriers can be determined for a given position and data rate requirement. Simulation results demonstrate the correctness of numerical evaluations.
