    • 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 ...
