摘要：
Provided is a method for receiving a DSS sequence and a DSS readback sequence, which is a function of a channel processing of the DSS sequence by a read channel. A coefficient cyclic equalizer vector is generated as a function of the DSS sequence and the DSS readback sequence. An error signal is generated as a function of a comparison of the DSS sequence and an equalization of the DSS readback sequence based on the coefficient cyclic equalizer vector. An unacceptable error signal indicates a need to adjust the coefficient cyclic equalizer vector to yield an acceptable comparison of the DSS sequence and an equalization of the DSS readback sequence based on the coefficient cyclic equalizer vector.
