    This paper studies the sum data rate that a Visible Light Communication (VLC) system with multiple users canachieve when phosphor-converted white LED panels are usedto provide illumination and communication simultaneously. ...
  • A new approach to exploit channel power imbalance in distributed antenna systems with fiber fronthaul 

    Dowhuszko, Alexis; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Restricted access - publisher's policy
    Cloud Modulation (CM) is a novel transmission method that mitigates the non-linear impairments introduced by the Radio-over-Fiber (RoF) links of a distributed antenna system. In CM, constant-envelope phase-modulated radio ...
  • Balancing egoistic and altruistic transmit beamforming in femtocell networks 

    Husso, Mika; Dowhuszko, Alexis; Hamalainen, K.; Pastore, Adriano; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Conference report
    Restricted access - publisher's policy
    In this paper, we study the balancing of egoistic (maximum-ratio, MR) and altruistic (zero-forcing, ZF) beamforming (BF) in femtocells through simulations. To investigate the achievable gains from operating between the ...
  • Distance-aware coordinated multi-point transmission for terahertz band communication 

    Dowhuszko, Alexis; Gil Jiménez, Víctor P.; Genovés Guzmán, Borja; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Restricted access - publisher's policy
    Terahertz (THz) band communication has abundant spectral resources to accommodate multiple broadband carriers. However, the strong path loss attenuation and the limited transmission power affect the maximum number of ...
  • Modeling the effect of non-linear distortion in a centralized RAN with analog optical fronthaul 

    Dowhuszko, Alexis; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    The Centralized Radio Access Network (C-RAN) architecture has potential to achieve the target goals that have been set for 5G. However, as the number of radio signals to be transported from the Centralized Base Station ...
