  • Blind channel estimation and data detection using hidden Markov models theory 

    Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Rodríguez Fonollosa, Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1997-01-01)
    Article
    Open Access
    In this correspondence, we propose applying the hidden Markov models (HMM) theory to the problem of blind channel estimation and data detection. The Baum–Welch (BW) algorithm, which is able to estimate all the parameters ...
  • 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
    Open Access
    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 ...
  • 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
    Open Access
    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 ...
