Abstract
Apparatus, computer program, and method for producing filter coefficients for an equalizer, the method includes the steps of: estimating a response (810) of a communication channel to a signaling pulse; estimating an autocorrelation (820) of noise and interference of the communication channel; computing an array (830) based on the estimation of the response of the communication channel to the signaling pulse and the estimation of the autocorrelation of the noise and interference of the communication channel; designating (840) at least one pivot position in the array; recursively performing the steps of: transforming the array (850) by a sequence of operations; storing (860) at least one element of the at least one pivot position; shifting (870) the at least one element of the at least one pivot position, thereby providing a shifted transformed array; determining (890) whether the shifted transformed array contains at least one non-zero element; and calculating (880) the filter coefficients based on the stored at least one element and the estimation of the response of the communication channel.
