    • On the inclusion of channel's time dependence in a hidden Markov model for blind channel estimation 

      Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Rodríguez Fonollosa, Javier (BOB WERNER IEEE COMPUTER SOCIETY PRESS, 1996)
      Text en actes de congrés
      Accés obert
      We introduce several modifications to the Baum&Welch (BW) formulas used to reestimate the parameters of a hidden Markov model (HMM). The estimated parameter is the channel impulse response (CIR) of a communication system ...

    • On the inclusion of channel's time dependence in a hidden Markov model for blind channel estimation 

      Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Faulí Prats, Claudio; Rodríguez Fonollosa, Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-05-31)
      Article
      Accés obert
      In this paper, the theory of hidden Markov models (HMM) is applied to the problem of blind (without training sequences) channel estimation and data detection. Within a HMM framework, the Baum–Welch(BW) identification ...

    • 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 ...

    • Probabilistic algorithms for blind adaptive multiuser detection 

      Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Zvonar, Zoran; Rodríguez Fonollosa, Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-11-30)
      Article
      Accés obert
      In this paper, two probabilistic adaptive algorithms for jointly detecting active users in a DS-CDMA system are reported. The first one, which is based on the theory of hidden Markov models (HMM’s) and the Baum–Wech ...
