Abstract :
System level performance of OFDM/ OFDMA is evaluated for various system parameters, such as frequency reuse factor, scheduling algorithm and sub-channel structures. Specifically, the generalized two step sub-channel/power allocation algorithm, with either aggregated or distributed sub-channel structure, is first extended to provide proportional fairness. Then, by simulation, the sector throughput is evaluated in practical OFDMA based cellular system environment with frequency reuse of 1 and 3, respectively.
