      Article
      Accés obert
      This article presents a TMN-compliant X interface, the so-called Xcoop interface, as a fundamental component of an operations system developed to cope with the challenges of multidomain, multitechnology networks. Defined ...
    • A hybrid-arq system for hf channels based on codeword partitioning 

      Serrat Fernández, Juan; Dalmau, J Royo (1996-04)
      Article
      Accés obert
      A technique by which the codewords of an error-correcting code are partitioned to obtain an error-detecting code with half the original length is described. It is intended to be used in a hybrid-ARQ system for achieving ...
    • Resource slicing in virtual wireless networks: a survey
