Interference Mitigation for OFDM-Based Joint Macro-Femto Cellular Networks
Femtocells underlay in macro-cellular network is becoming more popular in order to use spatial frequency reuse gain, extend the coverage and capacity. But interference mitigation is the main challenge for the system designer. Instead of using centralized coordination among base stations to mitigate or reduce interference caused by femtocells to macrocells, this paper investigates the dynamic di...
متن کاملScalable and Self-sustained Algorithms for Femto-Cell Interference Mitigation
Cellular networks are reaching their physical limits providing capacity that is almost near the Shannon theory. However, cellular usage is still increasing exponentially with hungry applications demanding higher data rates. As a result, designers are facing significant challenge in meeting the required demands. One promising solutions, being fostered by the 3GPP, is to increase the spectral eff...
متن کاملPerformance Study of Adaptive Video Streaming in an Interference Scenario of Femto-Macro Cell Networks
The demand for video traffic is increasing over mobile networks that are taking another shape by its heterogeneity. However, the wireless link capacity cannot cope with the traffic demand. This is due to the interference problem that can be considered as the most important challenge in heterogeneous networks. Consequently, it will result in poor service for the quality of video streaming such a...
متن کاملOn Uplink Interference Scenarios in Two-Tier Macro and Femto Co-Existing UMTS Networks
A two-tier UMTS network is considered where a large number of randomly deployed Wideband Code Division Multiple Access (WCDMA) femtocells are laid under macrocells where the spectrum is shared. The cochannel interference between the cells may be a potential limiting factor for the system. We study the uplink of this hybrid network and identify the critical scenarios that give rise to substantia...
متن کاملAdvanced Interference Management Techniques for Future Wireless Networks
In this thesis, we design advanced interference management techniques for future wireless networks under the availability of perfect and imperfect channel state information (CSI). We do so by considering a generalized imperfect CSI model where the variance of the channel estimation error depends on the signal-to-noise ratio (SNR). First, we analyze the performance of standard linear precoders, ...
