How Bad Is Interference in IEEE 802.16e Systems?
This paper presents a performance model for dynamic resource allocation in cellular deployments of IEEE 802.16e-like systems. More specifically, the authors derive a framework which allows to quantify the number of VoIP calls that can be supported in downlink of such systems purely based on the average SINR per terminal. The major difficulty to overcome is to predict the impact of dynamic resource allocations on the system performance in the presence of interference. They show that dynamic resource allocations perform a transformation of subcarrier SINR PDFs and derive an approximate, closed-form representation of these SINR PDFs.
