Abstract :
In this paper, we derived closed-form expressions for the SINR distributions in OFDMA cellular system using fixed relays. First of all, the intercell interference at the BS and the RS are characterized and it is found that the intercell interference power is successfully modeled as the average of it. From the interference power modeling, the pdfs of SINRs for the four uplink cases are analyzed. The analytical results are verified from computer simulations. The analytical results can be applied to evaluate various aspect of OFDMA cellular systems using fixed relays such as the average system capacity, the average system capacity for a specific region, the outage probability for a given QOS and so on.
