    Article
    Accés restringit per política de l'editorial
    Classical delay-lock loops (DLL) have beenwidely considered for code synchronization purposes inDS/CDMA systems, although they have not been devised foroperation when channel fading is present. This paper describes a new ...
  • Performance of Blind Equalization with Higher Order Statistics in Indoor Radio Environments 

    Valenzuela González, José Luis; Valdominos Bardají, Antonio; Casadevall Palacio, Fernando José (1997-05)
    Article
    Accés obert
    This paper analyzes the performance of blind equalization using the complex cepstrum of third-order moments applied to 4-QAM time division multiple access (TDMA) indoor radio communication systems. In particular, we have ...
