Adaptive Femtocell Design Scheme in Mobile Communication Systems

摘要

Mobile communication technologies have been evolving very rapidly and providing many advantages with mobile users. However, the amount of data traffic has increased significantly due to rapid expansion of mobile market. Recently, femtocell which is known as indoor base station is considered as the key solution to combat the data traffic. Femtocell provides mobile users with better quality of service. However, deployment of femtocell is not so easy due to inter-cell-interference (ICI) with existing macrocell. Signals from base stations are transmitted by a form of electronic magnetic waves. So, these waves undergo interference each other. Thus, this paper proposes the design scheme for femtocell which can reduce the influence of ICI. And also, proposed femtocell operates adaptively in accordance with reliability of system. With this proposed scheme, free and easy deployment of femtocell is expected.
