The N-dimensional optimization problem of a transversal filter equalizer with N-coefficients will be extended with the optimization of the sampling point to an (N+1)-dimensional problem. The derivation and computer-simulation of an iterative solution for this problem will be described. The convergence of this solution is shown to depend on the distortion of the channel and the relative choice of the shifting step of the sampling raster and the increment step of the coefficients.
