Abstract :
Turbo equalization is a receiver scheme intended to combat the detrimental effects of intersymbol interference (ISI) in digital transmissions protected by error-control codes (ECC). Traditionally, these equalizers are implemented with the optimal MAP (maximum a posteriori probability), or Bayesian algorithm. Thus, considering the close relationship between the fuzzy and Bayesian equalizers, this paper introduces a turbo-fuzzy equalization (TFEQ) approach to cope with ISI and high-power impulse noise effects in broadband digital communication channels. Simulation results for power line communication (PLC) channels evidence the applicability of our scheme to overcome the aforementioned impairments when high-rate transmission is considered
