    • Hybrid sparse linear array synthesis applied to phased antenna arrays 

      Yepes, Leonardo Fabio; Covarrubias, David; Alonso, Miguel A.; Ferrús Ferré, Ramón Antonio (2014-01-16)
      Article
      Accés restringit per política de l'editorial
      In this letter, a new hybrid technique to synthesize sparse linear arrays is proposed. This technique is based on the combination of two methods. As a first method, a deterministic synthesis algorithm is used to resolve ...

    • Millimeter-wave aperture synthesis radiometry for snow and ice mapping 

      Harvey, A.R.; Greenaway, A.H.; Camps Carmona, Adriano José; Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Bará Temes, Francisco Javier; Martín Neira, Manuel (1999)
      Text en actes de congrés
      Accés obert
      An outline design for a dual-band mm-wave polarimetric SAIR has been presented and is considered to be tractable. The envisaged application is for snow and ice mapping and ocean wind vector measurement. The vastly increased ...

    • Optimization of linear multielement antennas for selection combining by means of a Butler matrix in different MIMO environments 

      Grau Besolí, Alfred; Romeu Robert, Jordi; Blanch Boris, Sebastián; Jofre Roca, Lluís; Flaviis, Franco de (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-11-30)
      Article
      Accés obert
      An optimized linear multielement antenna (MEA) is presented for selection combining schemes that improves the selection diversity gain and selection diversity capacity in medium and low multipath environments, with ...

    • Performance evaluation of interference cancellation techniques using adaptive antennas 

      Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Rodríguez Fonollosa, Javier (IEEE Vehicular Technology Society, 1998)
      Text en actes de congrés
      Accés obert
      Two array-based algorithms, which jointly exploit or compensate for the spatial and temporal characteristics of the propagation channel, are proposed for intercell interference suppression in UMTS scenarios. The first one ...

    • Performance evaluation of space-time block coding using a realistic mobile radio channel 

      Carrasco Espinosa, Héctor; Delgado Penin, José Antonio; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2000)
      Text en actes de congrés
      Accés obert
      This paper presents a performance evaluation of space-time block coding (STBC) employing a realistic mobile radio channel model in macrocellular and urban environments. The bit error rate (BER) is computed by Monte-Carlo ...

    • Synthesis of large low-redundancy linear arrays 

      Camps Carmona, Adriano José; Cardama Aznar, Ángel; Infantes, D. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-12-31)
      Article
      Accés obert
      Aperture synthesis interferometric radiometers can overcome mass, weight and mechanical scan limitations of present-day radiometers. A full antenna array is “thinned” by eliminating selected antennas, while keeping all ...
