While femtocells provide various advantages for associated users, the occurred interference
on the macrocell layer remains a severe problem. To resolve such problems, various …

Due to significant advances in wireless access technologies and the proliferation of wireless
devices and applications, there is a fundamental change in wireless network traffic. As …

In this paper, we study the cognitive interference management (CIM) scheme in the
coexistence networks of macro-cells and femtocells. A single-channel detection based …

In this paper, we propose two-hop user-deployable indoor relays for CDMA systems with
signal bandwidth 5 MHz or less. We assume concurrent relaying wherein macro base …

In this paper, we investigate the interference mitigation in femtocell networks, where
femtocell access points (FAPs) are allowed to cooperate as different cooperative groups to …

Femto-cells deployment in today's cellular networks came into practice to fulfill the
increasing demand for data services. However, interference to other femto and macro-cells …

A cognitive femtocell is a new small cell based on a smart home base station to solve the
spectrum-scarcity problem. Recently, dedicated resource allocation for cognitive femtocells …

Scarcity of bandwidth and usage inefficiency of frequency band encourage of using
cognitive radio technology. Being motivated by green wireless communication makes us …

Wireless communication has involved relentless years of research and design and
comprises cellular telephony, broadcast and satellite television, wireless networking to …
