We propose user-deployable closed-access indoor relays for throughput improvements in
the downlink of LTE (long-term evolution) cellular system. The relays are assumed to be …

Due to numerous base stations (BSs) being randomly deployed in ultra-dense networks
(UDNs), the co-tier interference and cross-tier interference become more and more serious …

In order to mitigate the interference for macrocell users caused by deploying femtocells
(home base-station) in a long term evolution (LTE) system, a hybrid spectrum access model …

There is a large demand for applications of high data rates in wireless networks. These
networks are becoming more complex and challenging to manage due to the heterogeneity …

The increasing demand for high-speed data service triggers researchers investigating and
developing mobile wireless technology for indoor services. Some types of small cellular …

In two-tier femtocell networks, the femtocell users (FUs) can be admitted to the femto base
stations (FBSs) provided that the interference to the primary users (PUs) is no higher than …

요 약본 논문에서는 이종네트워크에서 펨토셀의 전력제어 기법을 게임이론을 이용해 정의한다.
저전력으로 고품질의통신환경을 제공하는 펨토셀은 여러 장점으로 인해 최근 이슈화 되고 …

Cognitive radio (CR) has recently become one of the most intensively studied paradigms in
wireless communications. In its broadest sense, a CR can be thought of as an enhanced …

Cognitive Radios are considered a standard part of future heterogeneous mobile network
architectures. In this chapter, a two tier heterogeneous network with multiple Radio Access …

In this paper, we consider femtocell CR networks, where femto base stations (FBS) are
deployed to greatly improve network coverage and capacity. We investigate the problem of …
