Coefficients - delay simultaneous adaptation for linear transversal equalizers on nonminimum phase channels

An efficient adaptation technique of the delay is introduced for accomplishing more accurate adaptive equalization. It is focused on the adaptive Butler-Cantoni (ABC) equalizer, which can deal easily with a variable delay for each iteration and the adaptation is conducted with channel estimation. The delay is adapted by checking the first and last elements of the coefficient vector for the ABC equalizer and it results in a linear transversal equalizer (LTE) providing a lower mean square error (MSE) than the other LTEs with the same order. The performance of the ABC equalizer with the delay adaptation is confirmed by computer simulations.
