  • De-hyping transmit diversity in modern MIMO cellular systems
    Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    A contemporary perspective on the tradeoff between transmit antenna diversity and spatial multi-plexing is provided. It is argued that, in the context of modern cellular systems and for the operating points of interest, ...
  • Fading models and metrics for contemporary wireless systems
    Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The purpose of this paper is to examine (1) some of the models commonly used to represent fading,/nand (2) the information-theoretic metrics most commonly used to evaluate performance over those models. We raise the question ...
  • Optimum pilot overhead in wireless communication: a unified treatment of continuous and block-fading channels
    Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in wireless fading channels is investigated, and the dependence of this overhead on various system parameters of interest (e.g., fading rate, signal-to-noise ratio) is quantified. The ...
  • What is the value of joint processing of pilots and data in block-fading channels?
    Jindal, Nihar; Lozano Solsona, Angel; Marzetta, Thomas L. (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The spectral efficiency achievable with joint processing of pilot and data symbol observations is compared with that achievable through the conventional (separate) approach of first estimating the channel on the basis of ...
