Summary:A digital signal processor (DSP) operating within, for example, an optical receiver wherein the DSP processes complex sample streams derived from a received digitally modulated optical signal, the DSP configured to perform a method comprising: using a filter adaptation algorithm (FAA), processing digitized complex sample streams for each of a sequence of unitary matrix different starting conditions associated with the FAA to establish a converged FAA.
