SINR and throughput enhancement in LTE-Advanced

Manifold processing approaches have contributed to LTE such a new version named LTE-A (Long Term Evolution-Advanced) have been defined. Among these approaches, we can e.g. cite those named CoMP, MIMO...Nevertheless, thanks to interference´s presence, a QoS degradation could sometimes be observed. For that, we will show in this paper, what and how this deficit has affected the studied network. Towards the establishment of the SINR, we will mainly describe how intercellular interference affect throughput for an LTE-A network´s macro user. Simulation results show how SINR and throughput´s vary reversely to femto cell number in the macro serving cell.
