Abstract :
In this paper, we evaluated effects of ICI (inter-cell interference) on an OFDM (orthogonal frequency division multiplexing) based wireless communication system´s reverse link capacity and suggested macroscopic diversity oriented resource allocation scheme to reduce interference and enhance reverse link capacity. For this, the exact amount of ICIs in the system is measured and represented as a closed form.
