Power line communication (PLC) continues to draw increasing interest with a potential for a wide range of appli cations including cost-free last-mile communication solution and smart grid monitoring. However, signals transmitted through the power lines deteriorate badly due to the presence of severe inter symbol interference (lSI) and harsh impulsive noise. This work studies reliable communication over narrow-band power lines by exploiting new ways of turbo equalization that is specifically designed for PLC. By introducing useful precoding to reshape lSI, optimizing maximum a posteriori (MAP) detection to specifically address the random impulsive noise, and performing soft iterative decision refinement, the new equalizer demonstrates a gain significantly better than the existing turbo equalizers.

“…Traditional channel equalizers, including transversal equalizers, decision feedback equalizers (DFE) and maximumlikelihood sequence equalizers (MLSE), are optimized under Gaussian noise. In PLC systems, nonlinear equalizers such as radial basis function (RBF) networks and fuzzy equalizers [5]- [8] are also favorable choices, and several studies have demonstrated their good performances in the presence of serious uncertainty posed by the pulse noise.…”

Power line communication continues to draw increasing interest by promising a wide range of applications including cost-free last-mile communication solution. However, signal transmitted through the power lines deteriorates badly due to the presence of severe inter-symbol interference (ISI) and harsh random pulse noise. This work proposes a new precoded turbo equalization scheme specifically designed for the PLC channels. By introducing useful precoding to reshape ISI, optimizing maximum a posteriori (MAP) detection to address the non-Gaussian pulse noise, and performing soft iterative decision refinement, the new equalizer demonstrates a gain significantly better than the existing turbo equalizers.
