Interference Management in Femtocells
IEEE Communications Surveys and Tutorials, 2013 Increase in system capacity and data rates can be achieved efficiently in a wireless system by getting the transmitter and receiver closer to each other. Femtocells deployed in the macrocell significantly improve the indoor coverage and provide better user experience.

Opportunistic interference management
2009 IEEE International Symposium on Information Theory, 2009Interference is a central feature of the wireless channel. However, in many cases, the interferer's activity can be bursty and it is overly pessimistic to assume that interference is always present. In this paper, we use a degraded message set formulation of the two-user interference channel to study the statistical gains that can be harnessed from ...

Interference management and handoff techniques
IEEE Vehicular Technology Magazine, 2009Intersector interference management is crucial in universal frequency reuse systems like OFDMA. In this article, we described advanced interference management techniques for future OFDMA communication systems. Such techniques include dynamic frequency reuse, intersector interference-based power control, and effective intersector handoff using disjoint ...

Interference management through cooperation
2009 IEEE International Symposium on Information Theory, 2009We consider a two-user interference channel where the source/destination nodes can cooperate with each other by virtue of being able to both transmit and receive. For the full-duplex mode of operation, we characterize the sum capacity of a linear deterministic channel exactly, and that of the Gaussian channel up to a constant number of bits.

Dynamic Interference Management in Femtocells
2012 21st International Conference on Computer Communications and Networks (ICCCN), 2012Femtocells are tiny, low-cost, customer-deployed cellular base stations that are designed to provide supplementary coverage to existing wireless networks. However, naive femtocell deployments can cause pilot pollution and raise interference levels for users connected to macrocells, particularly when the local density of femtocells is very high, such as

Interference management in heterogeneous network
7th International Conference on Communications and Networking in China, 2012Inter-cell interference is the main factor influencing performance in future cellular mobile systems. Interference management has become an important issue in system design, especially in heterogeneous networks since interference is more severe. To combat the interference, coordination between cells in heterogeneous network is considered.

Interference Management of OFDMA Uplinks
2007 IEEE 65th Vehicular Technology Conference - VTC2007-Spring, 2007The next generation of wireless networks will use OFDMA (orthogonal frequency division multiple access) technology in the uplink. In OFDMA, the uplink resources assigned to a user are called tiles each of which consists of a subset of consecutive subcarriers.

Interference Management versus Interference Cancellation: SATCOM Case
2011Interference management and interference cancellation are addressed in the satellite communication (SATCOM) system. We first introduce the two options for a multibeam payload: flexible (FLEX) where allocation is fully flexible in the frequency domain, and conventional on which beamforming (BF) is applied. Further, two optimization problems are proposed,
