Abstract

A system and method are disclosed for generating a calibration sequence of multilevel symbols includes generating subsequences of digital values selected from a range of digital values using a maximal length shift register. The subsequences have a given subsequence length. The range of digital values is mapped onto a set of multilevel symbols and the multilevel symbols corresponding to the generated digital values are output to a write strategy processor.
