Novel Interference Avoidance Approach for Femtocell Networks
Short range, low power, plug and play femtocell improves indoor service availability with higher data rate, better voice quality, extended cell edge coverage, network traffic offloading and negligible greenhouse gas emissions. However, due to frequency reuse, edge macrocell users are subjected to severe uplink interference from co-channel deployed femtocell in the same province. Transmit power ...
متن کاملCo-tier and Co-channel Interference Avoidance Algorithm for Femtocell Networks
Femtocells are regarded as a milestone for next generation cellular networks. As femtocells are deployed in an unplanned manner, there is a chance of assigning same resource to neighboring femtocells. This scenario may induce co-channel interference and may seriously affect the service quality of neighboring femtocells. In addition, the dominant transmit power of a femtocell will induce co-tier...
متن کاملDownlink interference minimization in cooperative cognitive LTE-femtocell networks
Femtocell is considered to be one of the most promising solutions for future indoor wireless communication. Due to the scarcity of spectrum resources, femtocells need to share the spectrum with other networks, which will inevitably bring in severe interference. Therefore, minimizing the cross-tier and co-tier interference while maintaining high system throughput or spectrum efficiency is one of...
متن کاملDownlink Interference Analysis in LTE-Femtocell Networks
Aiming to cope up with relentless wireless traffic and improving link quality against high wall penetration loss, Third Generation Partnership Project proposed the heterogeneous deployment of low power indoor hot spots such as Femtocell Access Points (FAPs) over the existing cellular network topology. In this two-tier heterogeneous network (HetNet) where femtocells coexist with macrocell, the F...
متن کاملHandset Antenna Diversity for Downlink Co-channel Interference Rejection
We report an investigation into the interference rejection capabilities of a dual antenna system on a mobile telephone prototype for the 1800 MHz band. The investigation is done by means of narrowband downlink channel measurements in a microcellular-like environment. Complex signal samples are used in order to investigate the interference rejection gain with di erent diversity combining schemes...
