Abstract
A time-domain equalizer includes a delay circuit, a weighting circuit, a controller and a summation circuit. The delay circuit receives an equalized signal and accordingly generates M delayed signals for an equalized signal. The weighting circuit applies an mweighting of M weightings to an mdelayed signal of the M delayed signals to generate an mweighted signal. The summation circuit sums up the M weighted signals, according to which the equalized signal is updated. The controller iteratively updates the M weightings according to a vector {right arrow over (e)}=[e. . . e], where the symbol eis defined as e=Σ(z[k]*z[k−D]*), the symbol n is an iteration index, k is a sample index, z[k] is a ksample of the equalized signal, j is an integer index between 1 and M, and Drepresents a time delay amount corresponding to a jdelayed signal of the M delayed signals.
