Interference Avoidance Using TDMA-Beamforming in Location Aware Small Cell Systems

Applied Sciences, 2019
It is ascertained that the current communication systems will not be able to support the future network demands due to the increasing traffic, limitation of frequency resources, and high level of interference.

Opportunistic Topological Interference Management [PDF]

IEEE Transactions on Communications, 2019
The topological interference management (TIM) problem studies the degrees of freedom (DoF) of partially- connected interference networks with no channel state information (CSI) at the transmitters except the network topology (i.e., partial connectivity). In this paper, we consider a variant of the TIM problem with uncertainty in network topology, where

Interference Steering to Manage Interference

, 2017
To enable densely deployed base stations (BSs) or access points (APs) to serve an increasing number of users and provide diverse mobile services, we need to improve spectrum utilization in wireless communication networks. Although spectral efficiency (SE) can be enhanced via smart and dynamic resource allocation, interference has become a major ...

Interference Steering to Manage Interference in IoT

IEEE Internet of Things Journal, 2019
Internet of Things (IoT) is a new paradigm that involves the interconnection of thousands of devices and home appliances. Due to the scarcity of the spectrum suitable for wireless electromagnetic transmission, many communication systems and devices are close to each other, or even overlapping in spectrum, thus incurring complicated interference ...

Downlink Beamforming Strategies for Interference-Aware NGSO Satellite Systems

IEEE Open Journal of the Communications Society
An important part of designing non-geostationary satellite orbit (NGSO) constellations is to ensure that they can co-exist with the legacy geostationary satellite orbit (GSO) systems in terms of interference levels.

Optimal Power Allocation Based on Metaheuristic Algorithms in Wireless Network

Mathematics, 2022
An optimal power allocation is a fundamental challenge for massive multiple-input–multiple-output (MIMO) systems because the power allocation should be acclimated to time-varying channels and heavy traffic conditions throughout the communication network.

Topological Interference Management for MIMO Interference Broadcast Channels [PDF]

IEEE Access, 2019
In this paper, we investigate the topological interference management (TIM) for MIMO interference broadcast channels (IBC) under the fixed topology, where only topology information is needed to cancel the inter-cell interference (ICI). For the single user case, where the MIMO IBC network is reduced to the MIMO interference channel (IC) networks, we ...
