1. A method for an equalizer computation in a read channel of a media system, comprising: receiving an electrical communication of a data set separator sequence and a data set separator readback sequence, wherein the data set separator readback sequence is a function of a channel processing of the data set separator sequence by the read channel; and generating a coefficient cyclic equalizer vector as a function of the data set separator sequence and the data set separator readback sequence wherein the generating of the coefficient cyclic equalizer vector as a function of the data set separator sequence and the data set separator readback sequence includes: generating a data set separator readback vector as a function of a sampling of the data set separator readback sequence; generating a data set separator reference vector as a function of a filtered sampling of the data set separator sequence: and generating the coefficient cyclic equalizer vector as a function of the data set separator readback vector and the data set separator reference vector and wherein the generating of the coefficient cyclic equalizer vector as a function of the data set separator readback vector and the data set separator reference vector further includes: generating odd indices of the coefficient cyclic equalizer vector as a function of a diagonal matrix based on the data set separator readback vector and the data set separator reference vector; and generating even indices of the coefficient cyclic equalizer vector as a function of an interpolation of the odd indices of the coefficient cyclic equalizer vector.
