Learning-Based Resource Allocation Scheme for TDD-Based CRAN System
Sahar Imtiaz, Hadi Ghauch, M. Mahboob Ur Rahman +2
Explosive growth in the use of smart wireless devices has necessitated the provision of higher data rates and always-on connectivity, which are the main motivators for designing th…
Coordination and Antenna Domain Formation in Cloud-RAN systems
Hadi Ghauch, Muhammad Mahboob Ur Rahman, Sahar Imtiaz +1
We study here the problem of Antenna Domain Formation (ADF) in cloud RAN systems, whereby multiple remote radio-heads (RRHs) are each to be assigned to a set of antenna domains (AD…
Subspace Estimation and Decomposition for Hybrid Analog-Digital Millimetre-Wave MIMO systems
Hadi Ghauch, Mats Bengtsson, Taejoon Kim +1
In this work, we address the problem of channel estimation and precoding / combining for the so-called hybrid millimeter wave (mmWave) MIMO architecture. Our proposed channel estim…
Sum-rate Maximization in Sub-28 GHz Millimeter-Wave MIMO Interfering Networks
Hadi Ghauch, Taejoon Kim, Mats Bengtsson +1
MIMO systems in the lower part of the millimeter-wave spectrum band (i.e., below 28 GHz) do not exhibit enough directivity and selectively, as their counterparts in higher bands of…
User Assignment in C-RAN Systems: Algorithms and Bounds
Hadi Ghauch, Muhammad Mahboob Ur Rahman, Sahar Imtiaz +3
In this work, we investigate the problem of mitigating interference between so called antenna domains of a cloud radio access network (C-RAN). In contrast to previous work, we turn…
