Advancing Data Center Networks: A Focus on Energy and Cost Efficiency
Chkirbene, Zina; Hamila, Ridha; Al-Dweik, Arafat; Khattab, Tamer ( IEEE , 2023 , Article)Data centers serve as the backbone for cloud computing, enterprise services, and infrastructure-based offerings. One area of ongoing research in data center networking focuses on innovating new topologies for large-scale ... -
Beamforming OFDM Performance under Joint Phase Noise and I/Q Imbalance
Hamila, Ridha; Ozdemir, Ozgur; Al-Dhahir, Naofal ( IEEE , 2015 , Article)Phase noise (PHN) and in-phase/quadrature (I/Q) imbalance are two major RF impairments in direct-conversion wireless transceivers. Beamforming and orthogonal frequency division multiplexing (OFDM) schemes have been adopted ... -
Exact SINR analysis of OFDM systems under joint Tx/RX I/Q imbalance
Ozdemir, Ozgur; Hamila, Ridha; Al-Dhahir, Naofal ( IEEE , 2013 , Conference Paper)The direct-conversion architecture used for Orthogonal Frequency Division Multiplexing (OFDM) systems suffers from intercarrier interference (ICI) between image subcarriers in each OFDM symbol due to I/Q imbalance between ...
