Turbo-Fuzzy Equalization for Single-Carrier Power Line Channels

This paper introduces a turbo-fuzzy equalizer (TFEQ) to cope with the inter-symbol interference effects and impulsive noise occurrences in bandlimited digital communication channels, such as the indoor and outdoor power line circuits. We exploit a close relationship between the fuzzy and Bayesian equalizers to derive an adaptive nonsingleton turbo-fuzzy equalization technique. Generally speaking, the TFEQ is obtained by introducing an adaptive decision feedback nonsingleton fuzzy equalizer into the turbo equalization structure. Simulation results reveal the applicability of this approach to overcome the noise impairments in the power line frequency range for broadband applications.
