DEVELOPMENT OF AN ENHANCED ACTIVE POWER CONTROL TECHNIQUE FOR INTERFERENCE MITIGATION IN MACRO- FEMTO CELLULAR NETWORKS
ABSTRACT Femtocells are overlayed on existing Macrocells to form Macro-Femto heterogeneous network (HetNet), to reduce cost of mounting expensive macrocell nodes, improve cellular network capacity and throughput performance. However, HetNet has a major problem of cross-tier and co-tier interference, which hinders its optimal performance, especially when the network capacity expands. With emergence of 5G technologies, interference would become more consequential. Therefore, curbing the effect of this interference is indispensable to ...
