摘要：
A canonical piece-wise-linear filter (CPWL) realization is proposed as part of the scheme for non linear time - domain equalization (TEQ) aiming impulsive noise interference reduction in xDSL transmission systems. The resulting structure is discussed in the context of a VDSL system using the usual Reed-Solomon (RS) coding to prevent impulsive noise effects. Also, a recently introduced impulsive noise model is used in order to evaluate the new methodology. The scheme for impulse noise reduction presented can be used to obtain an alternative compromise between RS correcting capabilities and interleaving delay. Results obtained using probability of error as performance measure indicate promising results. Computer simulations are included that allow to verify the interesting properties of the training algorithm for the nonlinear TEQ proposed.
