    • A comparative study of STBC transmissions at 2.4 GHz over indoor channels using a 2 × 2 MIMO testbed 

      Ramírez García, David; Santamaría, Ignacio; Pérez Arriaga, Jesús; Vía, Javier; García-Naya, José A.; Fernández-Caramés, Tiago M.; Pérez-Iglesias, Héctor J.; González-López, Miguel; Castedo, Luis; Torres-Royo, José M. (Hindawi, 2008)
      [Abstract]: In this paper we employ a 2 × 2 Multiple-Input Multiple-Output (MIMO) hardware platform to evaluate, in realistic indoor scenarios, the performance of different space-time block coded (STBC) transmissions at ...
    • Blind channel identification in Alamouti coded systems: a comparative study of eigendecomposition methods in indoor transmissions at 2.4 GHz 

      Pérez-Iglesias, Héctor J.; García-Naya, José A.; Dapena, Adriana; Castedo, Luis; Zarzoso, Vicente (Wiley, 2008)
      [Abstract]: This paper focuses on blind channel estimation in Alamouti coded systems with one receiving antenna working in indoor scenarios where the flat fading assumption is reasonable. A comparative study of several ...
    • Evaluation of H.264/AVC over IEEE 802.11p vehicular networks 

      Rozas-Ramallal, Ismael; Fernández-Caramés, Tiago M.; Dapena, Adriana; García-Naya, José A. (SpringerOpen & European Association for Signal Processing, 2013)
      [Abstract]: The capacity of vehicular networks to offer non-safety services, like infotainment applications or the exchange of multimedia information between vehicles, have attracted a great deal of attention to the field ...
