      Text en actes de congrés
      Accés restringit per política de l'editorial
      The simulation of LTE and LTE-A at link level is a research topic for several COST IC1004 institutions. It was agreed in previous meetings that it would be useful to define a common set of scenarios for LTE and LTE-A link ...
    • On the use of mutual information at bit level for accurate link abstraction in LTE with incremental redundancy H-ARQ 

      Olmos Bonafé, Juan José; Serra, Albert; Ruiz Boqué, Sílvia; Latif, Imran (2012)
      Text en actes de congrés
      Accés restringit per decisió de l'autor
      Link abstraction methods are able to predict the BLER in multicarrier wideband systems using AMC techniques under multipath fading. The basic idea is to map the vector of the subcarrier SNR’s to a single scalar, the Effective ...
