Abstract

This paper describes a framework of link capacity analysis for interference mitigation of uplink Orthogonal Frequency Division Multiple Access systems. A Macroscopic Diversity Oriented Resource Allocation (MDORA) is performed via inter-cell coordination based on the location of Mobile Stations (MSs) by exploiting macroscopic diversity in the uplink transmission. In the numerical analysis, the Inter-Cell Interference is derived as a closed form over a multi-cell environment. Subsequent numerical results demonstrate that MDORA offers an efficient inter-cell interference mitigation and a throughput expansion. Moreover, when up-link sectorization is adopted, the MDORA scheme presents a lower inter-cell interference, a reduced outage probability and an improved throughput.
