An equalizer for processing blocks of data includes n-1 data shifters, n finite filters, an adder, and a controller. Each of the n-1 data shifters shifts the blocks of data. One of the n finite filters applies a corresponding set of finite filter coefficients to the blocks of data, and each of the other n-1 finite filters applies a set of finite filter coefficients to a corresponding output of the n-1 data shifters. Ghosts of the blocks of data are not eliminated as a result of the application of the n sets of finite filter coefficients corresponding to the n finite filters, and n>2. The adder is arranged to add outputs from the n finite filters. The controller is arranged to control the sets of finite filter coefficients corresponding to the n finite filters so that the addition performed by the adder substantially eliminates the ghosts.
