  • A unified treatment of optimum pilot overhead in multipath fading channels
    Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in single-user 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 ...
  • Are yesterday’s information-theoretic fading models and performance metrics adequate for the analysis of today’s wireless systems?
    Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    The purpose of this paper is to examine some of the models commonly used to represent/nfading as well as the information-theoretic metrics most commonly used to evaluate performance/nover those models. We raise the question ...
  • 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 ...
  • Mutual information of IID complex Gaussian signals on block Rayleigh-faded channels
    Rusek, Fredrik; Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    We present a method to compute, quickly and efficiently, the mutual information achieved by an IID (independent identically distributed) complex Gaussian signal on a block Rayleigh-faded channel without side information ...
  • 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 ...
  • Transmit diversity vs. spatial multiplexing in modern MIMO systems
    Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    A contemporary perspective on the tradeoff between transmit antenna diversity and/nspatial multiplexing is provided. It is argued that, in the context of most modern wireless/nsystems and for the operating points of interest, ...
  • 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 ...
