Interference mitigation using antenna selection for the heterogeneous networks

Interference Mitigation in CR-Enabled Heterogeneous Networks

The heterogeneous network (HetNet), which deploys small cells such as picocells, femotcells, and relay nodes within macrocell, is regarded as a cost-efficient and energy-efficient approach to resolve increasing demand for data bandwidth and thus has received a lot of attention from research and industry. Since small cells share the same licensed spectrum with macrocells, concurrent transmission...

Cooperative Interference Mitigation Algorithm in Heterogeneous Networks

Heterogeneous hetworks (HetNets) have been introduced as an emerging technology in order to meet the increasing demand for mobile data. HetNets are a combination of multi-layer networks such as macrocells and small cells. In such networks, users may suffer significant cross-layer interference. To manage this interference, the 3rd Generation Partnership Project (3GPP) has introduced enhanced Int...

Cooperative Interference Mitigation for Heterogeneous Multi-hop MIMO Wireless Networks

This paper explores a new paradigm for the coexistence among heterogeneous multi-hop networks in unplanned deployment settings, called cooperative cross-technology interference mitigation (CIM). CIM exploits recent advancements in physical layer technologies such as technology-independent interference cancellation (TIIC), making it possible for disparate networks to cooperatively mitigate the i...

Interference mitigation using random antenna selection in millimeter wave beamforming system

In multi-user beamforming systems, the inter-user interference are controlled by spatial filtering. Since the implementation of digital beamforming is difficult due to high hardware cost of large array system, the analog beamforming system with one phase shifter at each antenna element is considered with antenna selection scheme. However, the beamwidth is not sufficiently narrow to perfectly re...
